Thanks everyone for your input it helps me to understand this.
I've been in PT for a while now and I am in agony today. My PT said he doesn't know if this helping or hurting me more, he said we need to see what the doctor has to say at my next visit. He doesn't want to push me if it's causing more discomfort. I have crawling sensation & numbness,burning & sharp shooting pain.
My leg is killing me..I've taken more pain med's this afternoon than I did yesterday.
Mike...I've been in tears so much from the pain also...
daniella mentioned the patches and I am starting to wonder if they are doing more harm than good...I wondered this before I read any replies.

RSD is so tough to understand and treat. After PT my affected area became swollen also, along with swelling in my legs (fluid retention).

Anyone use a TENS unit? I know everyone is different..I am in need of some relief, as we all are.

Thanks again for sharing your experience with me.
