Ok, the PT eval. is tomorrow. I would suggest writing down all your pain symptoms so you can ask a lot of questions, and make sure he/she does a thorough eval of all areas that are hurting. There is so, so much can be affecting you right now. And actually a good PT may help with that. The buttock pain (which I continue to have) may be helped with some heat and massage and stim and other things a PT uses. Most PT's will do some treatment after they evaluate, and usually first time after surgery they ease you into it - at least mine did, thankfully. If he/she doesn't do some things to help you relax a little first (like some heat packs, ultrasound, etc.) maybe you can ask for some things that would help you relax before doing any exercises.
Don't be afraid to assert yourself - and remember it may turn out to be a wonderfully soothing experience. Or at least begin to give you some answers about all that pain.
Let us know what happens!
