Can Fibroids Cause Leg & Back Pain?

What Causes Fibroid Back and Leg Pain?

Fibroids that grow toward the back of the uterus can press against nerves that run through the pelvis, including branches that connect to the sciatic nerve.^[1] This pressure can send pain from the lower back, through the hip and buttock, and down the leg. The pattern can feel a lot like sciatica caused by a herniated disc. The exact spot where you feel pain depends on the size and location of the fibroid, which is one reason different types of fibroids can cause very different symptoms.

Common Fibroid Pain Patterns

Fibroid pain can show up in more than one place at a time. Here are the patterns reported most often.

Lower Back and Hip Pain

A fibroid that grows at the back of the uterus can press on the spine or nearby muscles. This pressure often leads to a dull, steady ache in the lower back and hips that can feel worse by the end of the day.

Sciatica-Like Leg Pain

When a subserosal fibroid presses on the sciatic nerve, pain can travel from the lower back down through the buttock and leg.^[1] This nerve-based pattern is the most common way fibroid leg pain shows up.

Can Fibroid Pain Reach the Knee?

Some women feel this nerve-based pain travel far enough down the leg that it seems to reach the knee, which is why “fibroids and knee pain” is a common search term. This is still pain coming from a nerve in the lower back, not from inside the knee joint itself. Pain centered inside the knee joint, especially with stiffness or swelling in the joint, is more often caused by arthritis, injury, or joint wear, none of which are related to fibroids.

Pelvic Pressure and Bloating

Many women feel pressure or fullness in the pelvis before pain ever reaches the leg. This pressure can also affect nearby organs, leading to bloating or a feeling of fullness that is separate from general fibroid pain symptoms in the back and legs.

What Does a Fibroid Flare-Up Feel Like?

A fibroid flare-up often feels like stronger cramping, pressure, or aching that shows up around your period and eases afterward. Some women also notice heavier bleeding during a flare-up, along with lower back or leg discomfort that is more noticeable than usual.^[2] Flare-ups do not look the same for everyone, since heavy menstrual bleeding and pain levels depend on the size, number, and location of your fibroids.

How to Relieve Fibroid-Related Leg and Back Pain at Home

While you decide on next steps, a few simple habits may help ease fibroid-related back and leg pain.

• Resting with a pillow under your knees can take pressure off your lower back
• A heating pad on your lower back or abdomen may relax tense muscles
• Gentle stretching or short walks can ease stiffness without overworking sore muscles
• Over-the-counter pain relief may help with mild discomfort, used as directed

These steps may offer temporary comfort, but they do not treat the fibroid itself, so pain is likely to return if the underlying fibroid is not addressed.

When to See a Fibroid Specialist

Back or leg pain that keeps coming back, gets worse, or shows up alongside heavy bleeding is worth having checked. A fibroid specialist can use imaging to see whether a fibroid is pressing on a nerve and explain your options, which may include a minimally invasive treatment like Uterine Fibroid Embolization (UFE). Not every fibroid needs treatment, so a specialist can also help you understand whether you may be a candidate for UFE based on your specific symptoms.
