I have internal RSD caused by several surgeries and i have to deal with 75lbs of abdominal swelling. at this point the doctors hav no clue how to get it off me. I take prednisone to keep it in check but it doesnt remove it, lasix doesnt either.

I take methadone a very small dose and use a fentanyl patch which has been a life saver, i also take neurotin. I am going to a new pain mgt specialist who is familiar with RSD at GW Hospital in Wash DC. I first go for a consultation, no treatment on that day. This doctor does ketamine infusions.
Im scared, will i feel like myself after an infusion? will i be able to drive? Will i get the infusion and stop wearing the patch? I was taking percocet and oxycontin for 5 years and it didnt handle my pain. I am finally pain free and afraid to have pain again. what exactly does a ketamine infusion fel like and what does it do? what questions do i ask the doctor?

Thank you!
