Hi Susan: I can't comment on the disability or the nerve block but I can tell you don't worry about the colonoscopy. After what you've gone through already, this will be nothing. The prep is the worse prt of it. If they try to give you GoLytely-ask them about Fleets Phospho-Soda. Golytely is a gallon jug of clear, sickening liquid and you have to drink it all. Fleets is not much better tasting (kind of like fizzy club soda) but its over much more quickly. There are tips the GI docs office gave me to keep it down-types of liquids to drink with it (rather than the water the instructions tell you)If you need these I can give you them, just let me know. I had no problems with it (Fleets) and it was a very gentle laxative. Golytely is torture. (a whole GALLON> GAG) Mag Citrate should be banned. You should be having the colonoscopy under waht they call "conscious sedation", unlike the sigmoidoscopy. If they aren't going to do this don't have it done with this doctor!!!! Conscious sedation consists of a pain killer and something like valium or versed. I just learned that you can have it done with just the pain killer (like demerol) because I hate having no recollection of the procedure. That gives me the creeps. My husband had it done (demerol and versed) and he said he watched a guided tour of his colon on the monitor with a strange detached feeling, no pain at all. You are able to respond to questions. Of course he had a normal colon with no adhesions pulling on the outside! They had to give me more med because I was "letting them know" it was painful. They did, and I have no recollection of the procedure at all, not even the pain I was having and letting them know about. Really though, I think you will find this procedure tolerable. Godd luck.
