After going to different doctors various times I finally had one 2 days ago who was willing to listen to me and try to help me. He put me on antibiotics for PID. But when I researched PID online, it says PID is caused by STDs, which I know I don't have, or by a miscarriage, which I also know I haven't had. Also my symptoms are not the same as the PID symptoms I have found online. I am leaning more towards ovarian cysts, endometriosis, uterine fibroids, or appendicitis. My main symptom is PELVIC PAIN. The pain encompasses my pelvis and all the way down but the pain is not urethra or vaginal pain - it is body pain, and even hurts a little down my inner thighs; also on the front towards my hips. It is CONSTANT. That whole area is also swollen, so much so that I don't fit into a lot of my pants. I have other symptoms such as upset stomach when I eat and others but my biggest problem is the pain. Any thoughts?
