I have had a general...but would really perfer a local if they would let me! This is based on hating being in hospital and wanting to get out ASAP!
It was 10 years ago since I had a general, and it was not something that I had a choice about, so they concentrated more on what my BG was at the time. I was nil by mouth, and had to go on a sliding scale...but still managed to hypo before theatre. They will always try and get T1s to have a local over a general...and my main problem is teeth, and have teeth extracted, roots extracted, and major canal work, all under local...with the "if it was anyone else, they would have had a general comment. To be honest, it was absolutely fine...and far better than the 2 day stay in hospital would have been!
Having said that though...it is your call, and if you want a general, then they should allow you your choice. Be prepared for a short stay in hospital though, and possibly having to change your insulin doses etc.
best of luck with the toe...they are so painful!
