Oh do I feel your frustration! I've had lower right quadrant pain for over a year and a half now, it can act up for a few months, then be fine for a few months. This new flare I'm in has lasted 3 weeks thus far. I've been thru CT scans, abdominal ultrasounds, pelvic ultrasounds, upper GI with small bowel follow through, and still no one finds anything. When my pain is severe enough, it can double me over, or I have to go and lay down. The pain can come and go and is usually sharp and stabbing, although it can be a good ache too. Advil and Tylenol don't do a thing. I also had a diagnostic pelvic laparoscopy when I had my gallbladder out 2 months ago. My ob/gyn said my pelvic had textbook pictures of perfect pelvic organs, including my appendix. I saw the pictures, and I have to agree. I saw my GI dr. last week and he said the only thing we haven't looked at is my colon, so he scheduled me for a colonoscopy which I'm completely terrified about! In the meantime, he gave me a prescription for Bentyl to try. I haven't filled it yet, maybe I will today. I hope you find some answers!
