Hey Cheryl, yeah I don't think a chiro would be bad thing to try. I've seen countless doctors over the last year and still haven't made much progress, so maybe it's time to try something different.
I've been analyzing the hell out of my recent buttock pain and it does seem to fit a back problem better than a fissure. It just doesn't feel like what I recall of when my fissure was acting up, and the two rectal exams I had done recently didn't hurt at all, which I know would most definitely NOT have been the case with a fissure :)
I think I'm going to pony up the dough for the lumbar MRI, see what the results are, and then see either a chiro or maybe PT depending on what the MRI finds. I've never heard of EMG testing for muscles before -- I wonder if they can do that for other muscle groups too. To be honest I've never put much faith in chiros, but I don't know how much faith I have in doctors anymore now, either, so it can't be any worse...
