I have pain in my right side. My appendicitis was taken out years ago in Australia. I recently had a colonoscopy, but the issue was discovered through an endoscopy. The medicine (for arthritis) I was taking was causing internal bleeding, I am no longer taking this medication and stopped well over a year ago. I just found out today they are suggesting another colonoscopy. I m afraid they will decide to also do another endoscopy. Bottom line, my insurance didn t pay the last time and I m still paying for those procedures. How do I know the colonoscopy is the correct procedure? I was given medicine for an ulcer and it has helped, but I feel like someone is using my stomach as a punching bag and it is different to fall asleep at night.
