What Does Fibroid Pain During Pregnancy Feel Like?

Fibroid pain during pregnancy often feels like a dull ache, sharp localized pain, or persistent cramping, and may radiate to the lower back.

Most people assume a fibroid during pregnancy means constant, severe pain. But the reality is more surprising — the majority of pregnant people with fibroids never feel any discomfort at all.

When fibroids do cause pain, the sensation is distinct. It can range from a dull pressure to sharp, stabbing pangs, often described as stronger menstrual cramps that linger. Understanding what to expect can help you recognize when it’s typical and when to call your provider.

What Fibroid Pain Actually Feels Like

Fibroid pain during pregnancy is often described as a dull ache or pressure in a specific area of the lower abdomen. Some people feel a constant, heavy sensation, almost like something is pressing from the inside.

Others describe sharp, localized pain that comes and goes. This type tends to happen when a fibroid sits near a ligament or nerve and gets stretched as the uterus grows. The pain can also radiate to the lower back or groin.

Unlike round ligament pain, which is brief and triggered by movement, fibroid pain can persist for hours or even days. Many people say it feels like strong menstrual cramps that don’t let up, especially during the second and third trimesters.

Why Fibroids Become Painful During Pregnancy

Fibroids are noncancerous growths in the uterine wall. During pregnancy, hormonal changes and physical stretching can make some fibroids cause trouble. Here are the most common reasons pain develops:

• Stretching and pressure: As the uterus expands, a fibroid can get pulled or pressed against surrounding organs and nerves, creating a dull ache or sharp twinge.
• Red degeneration: A fibroid can outgrow its blood supply, causing it to break down internally. This releases chemicals that trigger severe, localized pain — often described as a hot, burning sensation — and may come with fever.
• Torsion (twisting): A pedunculated fibroid — one attached by a stalk — can twist on its stalk during pregnancy, cutting off its blood supply. This causes sudden, intense pain that requires immediate evaluation.
• Fibroid location: A fibroid sitting near the round ligament can worsen normal round ligament pain, making every quick movement or sneeze more uncomfortable.

How Fibroid Pain Differs From Round Ligament Pain

Many pregnant people wonder if their pain is from a fibroid or from round ligament stretching. The two share some overlap, but they tend to feel different. Round ligament pain is typically a sharp, jabbing sensation in the lower abdomen or groin that lasts only seconds. It’s triggered by sudden movement, coughing, or changing position.

Fibroid pressure pain is more constant. It doesn’t come and go as quickly, and it often feels like a dull ache over the entire area where the fibroid sits. Medical News Today notes that most pregnant people with fibroids have no symptoms — see its fibroids asymptomatic pregnancy page for more detail on when pain becomes noticeable.

When Fibroid Pain Signals an Emergency

Most fibroid pain during pregnancy is manageable, but certain symptoms warrant a call to your provider or a trip to the hospital. The key is to watch for signs that a complication like red degeneration or torsion may be happening.

1. Fever with abdominal pain: This can indicate red degeneration or an infection. A temperature above 100.4°F with pain needs prompt medical attention.
2. Heavy bleeding: Any vaginal bleeding that’s heavier than spotting, especially with cramping, should be evaluated right away.
3. Sudden, severe pain: Pain that comes on abruptly and stays intense, particularly if it’s on one side, could signal fibroid torsion. Don’t wait it out.
4. Difficulty urinating or passing stool: A fibroid pressing on the bladder or bowel can cause obstruction, which requires quick care.

If you experience any of these, contact your obstetrician or go to the emergency room. Pain alone without these red-flag signs is more often manageable at home.

Managing Fibroid Pain During Pregnancy

For typical fibroid pain that doesn’t involve emergency signs, simple measures can help. Rest is often the most effective — lying on your side takes pressure off the uterus and can ease the ache. Staying hydrated and using gentle stretching or a warm compress (not hot) on the area may also provide relief.

Acetaminophen (Tylenol) is generally considered safe during pregnancy for short-term pain, but you should check with your provider before taking any medication. Cleveland Clinic’s uterine fibroids definition page notes that most people with fibroids need no special treatment during pregnancy, but when pain is bothersome, these strategies can help.

It’s worth knowing that most fibroids do not grow during pregnancy — only about one-third may increase in size, usually in the first trimester. Pain is most common for fibroids larger than 5 centimeters and tends to appear in the second or third trimester.

The Bottom Line

Fibroid pain during pregnancy is real but not universal. When it does happen, it typically feels like a dull ache, persistent pressure, or cramping that’s more constant than round ligament pain. Most cases are manageable with rest and simple home care.

Your obstetrician can review your fibroid’s size and location on ultrasound and recommend pain relief options that are safest for your specific situation, especially if your symptoms change or worsen as your pregnancy progresses.
