My pain started last July of 2016...I've had 3 yes 3 ct scans...one endo lap excision surgery this past April. Found out I have stage 2 endo but my pain has always been on my right side! At my post op appointment doctor said no endo was found in my right side!! My appendix was removed as a possible cause of pain. The odd thing is that before my surgery my pain would get better after taking birth control. Now the doctor is saying it might have been coinsidence!!! What?!?! That it might be an inguinal hernia but ct scans don't show anything!! It could be hidden but my pain is worse when I start bleeding! I am so confused and feel like it might be something more serious. I have horrible back pain and abdominal/pelvic/groin pain! Urogynecologist don't perform hernia surgeries which I don't understand especially if they are chronic pelvic pain specialist!! Someone please help! Anyone had onesided pain it feels like appendicitis but I don't have an appendix anymore!!
