I had scope 2 years ago. Went great. I was out before they even wheeled me into room. Next thing I knew they woke me and said "done!" Had one a few days ago. Was AWFUL!!! Same dr, supposedly same meds. Well was so sick from prep, felt lousy going into hosp. Felt procedure right away. Dr. tried 2x then said he couldn't do it. I'd have to have Virtual colonoscopy (which is something everyone should ask about. Same prep, but NO invasive procedure, no pain med. Basically a 3d xray!) I could not have tho because my insurance did not cover. He said I'd have to do barium enema same day. While waiting in recovery for my appt. I became diafuretic. Cold sweat, naseau. Nurse said she didn't see how I could do the enema that day. My dr. kept insisting. I was there, I was prepped, etc. Well then I threw up for next hour. She finally told dr. NO. I went home and proceeded to throw up for next 5 hours. My abs hurt like hell from all the dry heaving. I am so angry. I don't know what happened but I am pissed w/dr. Why was this experience so different? Why couldn't he finish? Why was I so violently ill from the meds if they were the same as 2 years before? I can't get in touch w/dr. til monday (today friday). Have bad family history on mothers side so unfort I will need these tests for rest of my life. I am only 44 but 2 siblings around same age had polyps and part of colon removed. I am so afraid of anything more to do w/these tests tho. Anyone have any answers for such a massive difference in experiences? Thanks.
