What causes pelvic pain?
I have been experiencing persistent pain in my pelvic area recently, and sometimes the pain radiates to the upper thigh and lower abdomen. The pain worsens after prolonged sitting or walking. I'm quite concerned and unsure what might be causing this. Could pelvic pain be caused by any serious diseases?

Pelvic pain can be caused by various factors. The following are some common causes of pelvic pain:
1. Muscle or ligament strain: There are abundant muscles and ligaments around the pelvis. Strenuous exercise, improper posture, or trauma may cause injury to these soft tissues, leading to pain.
2. Joint problems: Such as sacroiliac joint arthritis, an inflammatory condition affecting the sacroiliac joints, commonly seen in patients with ankylosing spondylitis.
3. Lumbar spine disorders: Conditions such as lumbar vertebral fractures, lumbar spinal stenosis, and lumbar disc herniation may also cause pelvic pain, as these conditions can affect nerves and muscles in the pelvic region.
4. Gynecological diseases: Women may experience pelvic pain due to gynecological issues such as endometriosis, ovarian cysts, uterine fibroids, or pelvic inflammatory disease.
5. Urinary system diseases: Conditions such as cystitis or kidney stones may also cause discomfort in the pelvic area.
6. Changes during pregnancy: During pregnancy, as the fetus grows, pressure on the pelvis increases. Combined with hormonal changes, this may lead to pelvic pain.
