Hello, I've been having this pain in my right pelvic and it goes to my side, to the back, and in the appendix area. I've gone for scan, HVS, stool, urine tests. The doctor said i have PID. I took antibiotics and it the pain reduced but comes back again after a week. I went to see a gyno,he said it's infection. He gave me antibiotics which reduced the pain and it's back again. What is the problem please. My kidneys lives lungs are ok. It is not appendicitis. For 9months now.
