Hi, How Are You? My Name Is Jay. I Had

Hi, how are you? My name is Jay. I had my first colonoscopy by a doctor in July, 2013; after that I had some heartburn, some burning sensation around my stomach for several weeks and then everything was normal. Then again I had a brief 5 min colonoscopy and biopsy on Dec 16, 2013. About 14 to 18 days later I started having very sharp pain with burning sensation internally above my rectum area, I told my family doctor, and those doctors who did the colonoscopies on me. None of them has done anything to cure my problem. A year half later my family doctor said I have H-Pylori for which I took anti-biotic drugs twice and I have still this severe pain in the above my rectum area. I strongly believe the last colonoscopy and biopsy may have infected my stomach. Would you please tell me what I might have as my problems and what I should do. (Though first colposcopy polyp test borderline cancer related, later CT scan, Octreotide scan done in 2013 and 2014 showed no sign of cancer )
