Lower back pain is a widespread issue, and it’s known to affect women more frequently and become a chronic problem compared to men. While anyone can experience back discomfort, certain conditions and life stages unique to women can make them more susceptible. If you’re a woman wondering, “why does my lower back hurt?”, you’re not alone. This article will explore the common reasons behind lower back pain in women, helping you understand the potential causes and when to seek medical advice.
Several factors contribute to women’s increased vulnerability to back pain, and some conditions are even exclusive to women. Often, back pain issues become more prevalent after menopause, typically after the age of 50. Let’s delve into some of the key reasons why women experience lower back pain.
1. Piriformis Syndrome
Piriformis syndrome is a condition characterized by pain stemming from spasms in the piriformis muscle. This large muscle is situated deep within the buttock and when it spasms, it can lead to significant discomfort. Women are more prone to piriformis syndrome due to hormonal fluctuations and pregnancy-related pelvic changes.
Piriformis syndrome frequently results in irritation or compression of the sciatic nerve, mimicking the symptoms of sciatica. The pain associated with piriformis syndrome can include:
- Chronic pain in the buttock and hip area, which intensifies with hip movements.
- Pain upon getting out of bed.
- Difficulty sitting for extended periods.
- Pain radiating down the back of the thigh and leg.
Typically, these symptoms ease when lying on your back.

2. Sacroiliac Joint Dysfunction
Sacroiliac joint dysfunction, also known as SI joint pain or sacroiliitis, refers to pain originating from the sacroiliac (SI) joint. This joint connects the base of your spine to your pelvis and problems here are a frequent source of lower back pain.
Anatomical differences in women contribute to a higher risk of SI joint issues. Women generally have a smaller SI joint surface area compared to men, leading to concentrated stress on the joint. Additionally, the sacrum in women tends to be wider, less curved, and tilted further backward, which can predispose them to SI joint misalignment, particularly in younger women.
Sacroiliac joint dysfunction can also produce sciatica-like symptoms. Common symptoms include:
- Lower back pain.
- A persistent, dull ache in the buttock area, occasionally escalating to sharp pain.
- Sharp, stabbing, or shooting pain extending down the thigh, usually not beyond the knee.
SI joint pain often worsens when sitting, lying on the affected side, or climbing stairs.
3. Spinal Osteoarthritis
Osteoarthritis, or wear-and-tear arthritis, affecting the facet joints of the spine (the joints connecting vertebrae) is common, especially among women. The risk increases with age and weight.
Osteoarthritis of the Spine involves the breakdown of cartilage in the facet joints. This cartilage normally acts as a cushion, and without it, bones may rub together, causing pain. Osteoarthritis in the lower back can manifest as:
- Pain in the upper or lower back, groin, buttocks, and thighs.
- Morning stiffness and back pain.
- Episodes of severe pain flares.
The pain may be localized to one side of the back, intensify with applied pressure, and find relief when bending the spine forward.
4. Degenerative Spondylolisthesis
Degenerative spondylolisthesis occurs when a vertebra in the spine slips forward over the vertebra below it due to degeneration. This condition is more prevalent in post-menopausal women because of reduced estrogen levels.
Lower estrogen levels contribute to increased vertebral disc degradation and ligament loosening, which stabilize the vertebrae, leading to spinal instability. The higher incidence of spinal osteoarthritis in this age group further elevates the risk of vertebral slippage.
Degenerative spondylolisthesis can result in:
- Lower back pain with radiating pain into the legs.
- Neurogenic claudication, characterized by leg pain while walking, if the spinal cord is compressed.
Bending forward typically provides pain relief.
5. Coccydynia (Tailbone Pain)
Coccydynia, or tailbone pain, typically arises from trauma to the coccyx, the tail end of the spine. Women are more susceptible to this condition due to pelvic shape and angle differences and the potential for injury during childbirth.
Coccydynia (Tailbone Pain) can cause pain while:
- Sitting down.
- Leaning backward while seated.
- Sitting on hard surfaces.
- Standing up from a seated position.
Tailbone pain is usually relieved immediately upon standing. Individuals with coccydynia may prefer to sit leaning forward or shift weight to one buttock to avoid pressure on the tailbone.
6. Endometriosis
Endometriosis is a gynecological condition exclusive to women, where tissue similar to the uterine lining grows outside the uterus.
Endometriosis can cause a range of symptoms, including:
- Painful menstrual cycles with severe pelvic and lower abdominal pain.
- Pain in the genital area.
- Lower back pain, particularly during menstruation.
Pelvic and back pain associated with endometriosis can become chronic and worsen during menstrual periods.
7. Spinal Osteoporosis Fractures
Osteoporosis is a condition characterized by decreased bone density, making bones brittle and prone to fractures. Post-menopausal women are significantly more likely to develop osteoporosis than men, largely due to estrogen deficiency, earlier bone loss, and a faster rate of bone loss.
Osteoporosis itself can cause bone pain, but more frequently leads to compression fractures in the spine, resulting in sudden, acute back pain. Spinal compression fractures can cause:
- Sudden, localized back pain, often in the mid-back or the region between the mid and lower back.
- Pain that may radiate to the front of the body, sometimes mistaken for heart or lung issues.
Depending on the severity, spinal compression fractures can be a medical emergency.
Lifestyle Factors and When to Seek Help
Beyond these specific conditions, general life cycle changes in women, including pregnancy, childbirth, hormonal imbalances, and weight gain (especially abdominal weight), can contribute to lower back pain. These factors can trigger a series of events that ultimately lead to back discomfort.
If your lower back pain persists despite self-care measures, causes neurological symptoms like numbness or weakness, or interferes with your daily life, it’s important to consult a doctor. A medical professional can accurately diagnose the cause of your pain and recommend appropriate treatment. They can also advise on lifestyle adjustments, such as an anti-inflammatory diet and a structured exercise program, to help prevent future occurrences of back pain.
