10 Symptoms of Pelvic Inflammatory Disease

7. Annoying Lower Back or Leg Pain

Pelvic pain or pain in the lower or even upper abdomen due to PID can spread to the lower back or legs. The pain may feel stronger during urination, bowel movement, or after sex. It could be accompanied by constant cramps or cramping that comes and goes. The pain may continue for days, become worse or return after treatment with over-the-counter painkillers. Because PID is usually caused by an STI or bacterial infection, it must be treated with antibiotics.
