I have had lower right side pain for over 4 months. In December I was diagnosed with an ovarian cyst and had a repeat ultrasound to make sure it was very a cyst. By then the cyst was gone (now have one on my left side), but I'm still having pain. No fever and no elevated white count, so they say it's not my appendix. I am going to consult with a GI dr next week.
Def. do this! You can ask that your Dr. recommend a CT scan, too. However, these are not fun. Drinking that goo is nasty and the thought of having to do it makes me want to hurl. Even after antibiotics at home to get the wbc count back to normal, I still had an infected appendix and walked around w/it for almost 2 months! These things can be like a volcano -- stewing and not doing much until they decide to blow.
