My heart melts hearing you... I'M THE SAME WAY!!
I would recommend finding a GI doctor or some type of specialist... Again, like I said, my mom was my advocate. She's in the medical field and there are many doctors she has run into who are too "easy-going" and have missed things (ex. a girl I went to HS with was a star athlete and began having trouble breathing and he gave her an inhaler diagnosing "asthma" for the final 3 yrs of HS; she had non-hodgkin's lymphoma and a grapefruit size tumor on her lung... all he would've had to do is a freaking x-ray?!)... Octreotide scans detect carcinoids... ask about one... but don't do them too often, b/c I've heard that you should never have more than 2-3 in a lifetime b/c you body stops reacting to the nuclear injection so they are just painfully pointless. I had 2, then my dr recommended a 3rd this yr, I declined at this point but will reconsider it in the next year or two. Carcinoids are VERY slow growing, so that gave me some peace of mind. What symptoms did you have that prompted you to want a colonoscopy? I had extreme varying bouts of nausea, extreme varying sleep patterns, flushing, bowel issues, etc... I still have digestive problems which the doctors have yet to figure out...Heck, I have little faith anymore, I really have just been experimenting and researching on my own for the last 9yrs... I sure am thinking about you... please keep me updated!!
