What causes left lower back pain in women?

Generally, left lower back pain in women may be caused by poor posture, excessive exercise, fasciitis, kidney stones, adnexitis, or other reasons. It is recommended to seek medical attention promptly, identify the cause, and receive symptomatic treatment under a doctor's guidance. Detailed explanations are as follows:

1. Poor Posture

Prolonged bending, hunching, sitting, or standing can strain the back muscles, causing left lower back pain in women. It is recommended to maintain good posture, avoid staying in the same position for long periods, and periodically stretch the back muscles. Exercises such as tilting the head backward, puffing out the chest, and raising the arms upward to stretch the body can help relieve muscle tension.

2. Excessive Exercise

Overexertion may cause muscle strain, sprains, or lactic acid buildup in the back muscles, resulting in pain in the left lower back. It is advised to stop exercising immediately and apply cold compresses within the first 72 hours to reduce pain and swelling. After 72 hours, heat therapy may be applied to promote blood circulation and aid recovery.

3. Fasciitis

The fascia in the lower back may develop aseptic inflammation—known as fasciitis—due to trauma, overuse, or cold exposure, leading to pain in the left lower back, possibly accompanied by localized stiffness and tenderness. Appropriate heat therapy and massage may help improve blood circulation. It is also important to keep the lower back warm and avoid chilling.

4. Kidney Stones

Poor lifestyle habits and lack of physical activity may lead to kidney stones. These stones may move from the kidney into the ureter, causing severe and intolerable pain in the left lower back, often accompanied by nausea and vomiting. Treatment may include medications such as lithiasis granules, urolithiasis-clearing granules, and racemic anisodamine tablets, as directed by a physician.

5. Adnexitis

Infection with bacteria such as streptococcus or Escherichia coli may lead to infection of the fallopian tubes, ovaries, and surrounding tissues, causing adnexitis. Symptoms may include left lower back pain, fever, and loss of appetite. Treatment may involve medications such as ceftriaxone sodium for injection, cefoxitin sodium for injection, and levofloxacin hydrochloride tablets, as directed by a physician.

In daily life, it is important to ensure adequate sleep, avoid excessive fatigue, and consume more fresh vegetables and fruits such as cabbage, apples, and tomatoes to enhance immunity.
