Pelvic pain and back pain are among the most common complaints women experience at some point in their lives. While these symptoms are often blamed on muscle strain, posture, or gynecological conditions like endometriosis, another frequently overlooked cause is uterine fibroids. Understanding how fibroids contribute to discomfort can help women seek appropriate diagnosis and treatment sooner, improving quality of life.

This article explores the relationship between fibroids, pelvic pain, and back pain, explains why symptoms occur, and highlights when medical attention is necessary.

Understanding Uterine Fibroids

Uterine fibroids, also known as leiomyomas, are noncancerous growths that develop from the muscle tissue of the uterus. They vary widely in size, number, and location. Some women may have a single small fibroid, while others develop multiple fibroids that significantly enlarge the uterus.

Fibroids are extremely common, particularly during the reproductive years. Many women with fibroids experience no symptoms at all, but for others, fibroids can cause heavy menstrual bleeding, pelvic pressure, fertility issues, and chronic pain.

How Fibroids Cause Pelvic Pain

Pelvic pain is one of the hallmark symptoms associated with fibroids, especially when they grow larger or press against surrounding organs. The pain may be dull and aching or sharp and persistent, depending on the type and location of the fibroids.

Pressure and Crowding in the Pelvis

As fibroids increase in size, they occupy space within the pelvic cavity. This can create a sensation of heaviness, fullness, or pressure in the lower abdomen. Large fibroids and pressure symptoms often go hand in hand, as the uterus may expand to the size of a pregnancy, compressing nearby structures such as the bladder, bowel, and pelvic nerves.

This pressure can lead to:

• Constant pelvic discomfort
• Pain during prolonged standing or sitting
• Increased pain before or during menstruation

Degeneration of Fibroids

Fibroids require a blood supply to grow. When a fibroid outgrows its blood supply, it can begin to degenerate, causing sudden and sometimes severe pelvic pain. This pain may last for days or weeks and is often accompanied by inflammation.

Pain During Intercourse

Fibroids located near the cervix or lower uterus can cause pain during sexual activity. This symptom can significantly affect emotional well-being and intimate relationships.

The Link Between Fibroids and Back Pain

While pelvic pain is a well-known symptom, many women are surprised to learn that fibroids can also cause chronic lower back pain. In fact, pelvic and back pain linked to fibroids is a common but underrecognized issue.

Nerve Compression

The uterus sits close to nerves that run through the lower back and pelvis. When fibroids grow large enough, they can press against these nerves, leading to pain that radiates to the lower back, hips, or even down the legs. This type of pain may resemble sciatica and is often mistaken for a musculoskeletal problem.

Postural Changes

An enlarged uterus due to fibroids can alter posture and spinal alignment. The additional weight in the front of the body may strain the lower back muscles, leading to chronic discomfort, stiffness, and fatigue.

Referred Pain

Pain caused by fibroids in the pelvis may be “referred” to the lower back. This means the brain interprets the pain as coming from the back even though the source is the uterus.

Large Fibroids and Pressure Symptoms

Not all fibroids cause pain, but large fibroids are much more likely to produce noticeable symptoms. Large fibroids and pressure symptoms can affect multiple organ systems, compounding discomfort and pain.

Bladder Pressure

Fibroids pressing against the bladder can cause frequent urination, urgency, or difficulty fully emptying the bladder. This constant pressure may worsen pelvic pain and contribute to nighttime discomfort.

Bowel Compression

When fibroids push against the rectum or intestines, they can lead to constipation, bloating, and pain during bowel movements. Straining can further aggravate pelvic and back pain.

Impact on Daily Activities

Women with large fibroids may find it uncomfortable to bend, exercise, or lie flat. Activities that involve core muscles or prolonged standing can intensify symptoms, affecting work productivity and overall quality of life.

When Pain Signals a Need for Medical Evaluation

Pelvic or back pain should never be ignored, especially if it is persistent, worsening, or interfering with daily life. Women should consider seeking medical evaluation if they experience:

• Chronic pelvic pain lasting several months
• Lower back pain that does not improve with rest or physical therapy
• Heavy or prolonged menstrual bleeding alongside pain
• Rapid abdominal enlargement or visible bloating
• Pain during intercourse or bowel movements

A healthcare provider may perform a pelvic exam and imaging tests such as ultrasound or MRI to determine whether fibroids are the underlying cause.

Diagnosing Fibroid-Related Pain

Diagnosing fibroids is often straightforward, but linking them directly to pain requires careful evaluation. Imaging studies help determine the size, number, and location of fibroids, which can explain symptom patterns.

For example:

• Fibroids at the back of the uterus are more likely to cause back pain
• Subserosal fibroids (growing outward) often cause pressure symptoms
• Large intramural fibroids (within the uterine wall) may cause both pelvic and back pain

Understanding these distinctions helps guide treatment decisions.

Treatment Options for Painful Fibroids

Treatment depends on symptom severity, fibroid size, age, and reproductive goals. Options range from conservative management to surgical intervention.

Medications

Pain relievers such as NSAIDs may help manage mild discomfort. Hormonal therapies can sometimes reduce bleeding and slow fibroid growth, though they may not significantly shrink large fibroids.

Minimally Invasive Procedures

• Uterine artery embolization (UAE): Cuts off blood supply to fibroids, causing them to shrink
• MRI-guided focused ultrasound: Uses heat to destroy fibroid tissue

These options may relieve pressure-related pelvic and back pain without major surgery.

Surgical Treatments

• Myomectomy: Removal of fibroids while preserving the uterus
• Hysterectomy: Complete removal of the uterus, offering a permanent solution

Surgical treatment is often considered when large fibroids and pressure symptoms severely affect daily life.

Living With Fibroids: Managing Pain Holistically

In addition to medical treatment, lifestyle strategies may help reduce discomfort:

• Gentle exercise such as yoga or walking to ease stiffness
• Heat therapy for pelvic and lower back pain
• Maintaining a healthy weight to reduce pelvic pressure
• Stress management techniques to cope with chronic pain

While these approaches do not eliminate fibroids, they can improve overall comfort and well-being.

Conclusion

Pelvic pain and back pain are not just random aches that women must tolerate. In many cases, pelvic and back pain linked to fibroids is the body’s way of signaling an underlying issue that deserves attention. Fibroids—especially large ones—can exert pressure on pelvic organs, nerves, and muscles, leading to chronic discomfort that affects daily life.

Recognizing the connection between fibroids, pelvic pain, and back pain empowers women to seek timely diagnosis and appropriate treatment. With a wide range of medical and surgical options available today, no one has to suffer in silence. Early intervention can relieve pain, restore comfort, and improve long-term health outcomes.
