In my years working as a pharmacist, I have lost count of how many women have come to my counter asking for a painkiller for "period pain" — only for it to turn out later that they had an ovarian cyst they did not know about.
This happens more than most people realize. Ovarian cysts are extremely common. Many women have them at some point in their lives. And the frustrating truth is — most ovarian cysts cause no symptoms at all. They form silently, exist quietly, and often disappear on their own without the woman ever knowing they were there.
But some ovarian cysts do cause symptoms. And when they do, those symptoms are easy to confuse with period pain, gas, bladder problems, or even appendicitis. Women suffer for months — sometimes years — taking painkillers and antacids without anyone investigating the real cause.
Today I want to give you a clear, honest picture of what ovarian cyst symptoms actually feel like — based on what women have described to me at my pharmacy counter, combined with the pharmacological and clinical knowledge I have from my training.
What exactly is an ovarian cyst?
Before talking about symptoms, let me briefly explain what a cyst actually is — because many women are scared by the word and imagine something much worse than the reality.
An ovarian cyst is simply a fluid-filled sac that develops on or inside one of the ovaries. Think of it like a small balloon filled with liquid. Most cysts are functional — meaning they form as a normal part of the menstrual cycle and disappear on their own within one to three months without any treatment.
The ovaries normally produce small cyst-like structures called follicles every month as part of ovulation. Sometimes one of these follicles does not rupture and release an egg as it should — instead it keeps growing and becomes a cyst. This is called a functional cyst and it is completely benign in the vast majority of cases.
Other types of cysts — dermoid cysts, endometriomas, cystadenomas — are less common and may require medical attention. But the most important point is this: having an ovarian cyst does not automatically mean something is seriously wrong.
The silent majority — cysts with no symptoms
I want to be honest with you about something that many health websites do not emphasize enough. The majority of ovarian cysts — especially functional cysts — cause absolutely no symptoms. None. Zero.
They are discovered by accident — usually during an ultrasound done for a completely different reason, like a routine check-up, pregnancy scan, or investigation for something else entirely. A woman will be told she has a cyst and she will be shocked because she felt nothing unusual.
This is actually good news. It means that just because you read a list of ovarian cyst symptoms and recognize some of them does not necessarily mean you have a cyst. And it means that if you are told you have a small cyst, the absence of symptoms is completely normal.
When ovarian cysts do cause symptoms
Symptoms usually occur when a cyst is larger in size, when it has ruptured, when it has caused the ovary to twist (a condition called ovarian torsion), or when it is pressing on nearby organs like the bladder or bowel.
Here is what those symptoms actually feel like — described as closely as possible to what my patients have told me over the years.
1. Pelvic pain — the most common symptom
The most frequently reported symptom is a dull, heavy aching pain in the lower abdomen — specifically on one side. It is usually on the side where the cyst is located. Women often describe it as a feeling of heaviness or pressure rather than a sharp stabbing pain.
This pain can be constant or it can come and go. It often gets worse during periods, during or after sex, or when you have a full bladder or bowel. Many women who come to my pharmacy describe it as "something feels different about my period pain this time — it is heavier on one side and does not go away completely even after the period ends."
That last part — pain that continues even after the period is over — is an important clue. Normal period pain is tied to the menstrual cycle. Ovarian cyst pain can persist throughout the month, not just during periods.
2. Bloating and a feeling of fullness
Many women with ovarian cysts report feeling bloated even when they have not eaten much. The abdomen may feel swollen or distended. Some describe it as feeling like they are several months pregnant even though they are not.
This bloating is caused by the cyst taking up space in the pelvic cavity and pushing against the surrounding organs. A larger cyst can cause visible abdominal swelling that is actually noticeable when you look in the mirror.
This symptom is easy to dismiss as gas, constipation, or bloating from food — which is why many women do not connect it to a gynaecological problem. I have had patients who spent months taking antacids and gas tablets before an ultrasound revealed an ovarian cyst.
3. Pain during or after sex
Pain during sexual intercourse — medically called dyspareunia — is another common symptom of ovarian cysts. The pain is usually felt deep inside the pelvis, on the side where the cyst is, and can occur during or after intercourse.
Many women feel embarrassed to mention this symptom — even to their doctor. But it is a very important signal. Deep pelvic pain during sex that was not there before is something that should always be investigated by a gynaecologist. It can indicate not just a cyst but also conditions like endometriosis.
4. Urinary symptoms
If an ovarian cyst is pressing against the bladder, you may feel the need to urinate more frequently than usual — even when the bladder is not full. Some women also experience difficulty fully emptying the bladder or a feeling of pressure in the bladder area.
This symptom is almost always mistaken for a urinary tract infection. Women come to my pharmacy asking for medicines for UTI — frequent urination, pressure, discomfort — and have been treating it repeatedly without the symptoms fully resolving. In some of these cases, the real cause was an ovarian cyst pressing on the bladder, not a bacterial infection.
5. Bowel changes
A cyst pressing on the bowel or rectum can cause constipation, a feeling of incomplete bowel emptying, or pain when passing stools. Again — these symptoms are easy to attribute to diet or digestive problems rather than a gynaecological cause.
6. Irregular or painful periods
Ovarian cysts — particularly those related to hormonal imbalances like PCOS (Polycystic Ovary Syndrome) — can cause irregular menstrual cycles. Periods may become heavier, lighter, more painful, or unpredictable in timing.
PCOS is the most common hormonal disorder in women of reproductive age in India. It involves multiple small cysts on the ovaries combined with hormonal imbalance. If your periods have always been irregular and you have other symptoms like excess facial hair, weight gain, or acne — PCOS should be investigated with a doctor.
7. Nausea and vomiting
Some women experience nausea — particularly around the time of their period or when the cyst pain is at its worst. This is more common when a cyst is larger or when there is a complication like a ruptured cyst.
💊 Pharmacist Tip from Santosh
If you have been taking painkillers for lower abdominal pain every month for more than two to three cycles and the pain keeps coming back — please see a gynaecologist and ask for a pelvic ultrasound. Do not keep treating the pain without finding the cause. Pain that returns regularly is your body telling you something needs investigation, not just management.
Symptoms that need emergency attention — right now
Most ovarian cyst symptoms are manageable and not immediately dangerous. But there are specific symptoms that indicate a cyst may have ruptured or that the ovary has twisted — both of which are medical emergencies.
Go to a hospital emergency immediately if you experience:
- Sudden, severe pain in the lower abdomen — sharp, stabbing, much worse than usual period pain. This can indicate a ruptured cyst or ovarian torsion.
- Pain with fever and vomiting — this combination suggests possible infection or a serious complication.
- Feeling faint, dizzy, or like you might pass out — a ruptured cyst can cause internal bleeding which leads to these symptoms.
- Rapid breathing and a racing heartbeat — signs of internal bleeding or severe pain response.
- Shoulder tip pain — this sounds strange but blood from a ruptured cyst can irritate the diaphragm and cause referred pain to the shoulder. This is a serious emergency sign.
🚨 Do Not Wait — Go to Hospital Immediately
Sudden severe pelvic pain with dizziness, fever, or vomiting is a medical emergency. Do not take a painkiller and wait to see if it gets better. A ruptured ovarian cyst with internal bleeding needs immediate medical treatment. Call someone to take you to the nearest hospital emergency — do not drive yourself.
How ovarian cysts are diagnosed
The only way to confirm an ovarian cyst is through a pelvic ultrasound. This is a painless scan that gives the doctor a clear picture of the ovaries, the size and location of any cyst, and its characteristics — whether it is a simple fluid-filled cyst or something more complex.
A doctor may also order blood tests including a CA-125 test in some cases — this is a marker that can be elevated with certain types of ovarian cysts and ovarian cancer. However CA-125 is not a definitive cancer test — it can be elevated for many reasons including endometriosis and fibroids. Do not panic if your doctor orders this test — it is a precaution, not a diagnosis.
Ovarian cyst vs period pain — how to tell the difference
This is the question I get most often. And it is genuinely difficult to answer without an ultrasound — but here are the clues I look for when a patient describes her pain to me:
Normal period pain typically starts one to two days before the period, peaks on the first or second day, and then gradually improves. It is usually felt in the centre of the lower abdomen and responds reasonably well to Meftal Spas or Ibuprofen.
Ovarian cyst pain tends to be on one side rather than central. It may exist throughout the month — not just during periods. It may not respond as well to standard period pain medicine. And it is often accompanied by other symptoms like bloating, urinary changes, or pain during sex that normal period pain does not cause.
If your pain is one-sided, persistent beyond your period, and accompanied by bloating or other symptoms — please get an ultrasound.
Who is most at risk of ovarian cysts?
Ovarian cysts can affect any woman at any age — from adolescence through to after menopause. But certain groups are at higher risk:
Women of reproductive age — functional cysts are most common in women who are still having regular periods because cysts form as part of the ovulation process.
Women with PCOS — Polycystic Ovary Syndrome involves multiple small cysts on the ovaries and is one of the most common reasons for ovarian cysts in young Indian women.
Women with endometriosis — a condition where tissue similar to the uterine lining grows outside the uterus. It can form cysts on the ovaries called endometriomas or chocolate cysts.
Pregnant women — a corpus luteum cyst sometimes forms in early pregnancy. Most resolve on their own without any problem.
Post-menopausal women — while cysts are less common after menopause, they do occur and need more careful investigation when they do because the risk profile changes after menopause.
What to do if you think you have an ovarian cyst
If you have read through this article and recognize several of these symptoms in yourself — do not panic. But do not ignore it either. Here is what I recommend:
See a gynaecologist and ask for a pelvic ultrasound. This is the first and most important step. Without an ultrasound, neither your doctor nor a pharmacist can tell you with certainty whether you have a cyst or not.
Keep a symptom diary for two to three weeks before your appointment — note when the pain occurs, how severe it is, whether it is related to your period, and any other symptoms like bloating or urinary changes. This information helps the doctor enormously.
Do not self-medicate long-term. Taking painkillers every month without investigation is not managing your health — it is masking a problem that may need attention.
Frequently asked questions
Can I feel an ovarian cyst with my hand?
Very large cysts — typically above 5 to 6cm — may occasionally be felt as a mass in the lower abdomen. Smaller cysts cannot be felt from outside. Only an ultrasound can confirm a cyst regardless of size.
Can an ovarian cyst affect pregnancy?
Most functional cysts do not affect fertility or pregnancy. However certain types of cysts — particularly large endometriomas — can affect fertility. If you are trying to conceive and have been diagnosed with an ovarian cyst, discuss this specifically with your gynaecologist.
Will my ovarian cyst go away on its own?
Functional cysts — the most common type — very often resolve on their own within one to three menstrual cycles without any treatment. Your doctor will usually recommend a follow-up ultrasound after two to three months to confirm this. Other types of cysts may need monitoring or treatment.
Is ovarian cyst pain constant or does it come and go?
It varies. Many women describe the pain as coming and going — sometimes a dull ache for a few days, then nothing, then returning. Others have more constant discomfort. Pain that is sudden and severe and does not ease off is an emergency — do not wait in that situation.
Can stress cause ovarian cysts?
Stress does not directly cause ovarian cysts. However stress affects hormone levels — and hormonal imbalances are one of the contributing factors to cyst formation. Managing stress, getting adequate sleep, and maintaining a healthy weight all contribute to better hormonal balance and overall reproductive health.
