Hi,
I have RSD affecting my left arm, shoulder, arm , and hand. I have very little use of my left hand.
My neck muscles and down the left side of my back are always tense.
Nobody seems to know why but they are. Alot of times the pain from there is equal to or exceeds that of the RSD.
I understand what you are going through.
I dont take much medication by choice because I don't wanna live as a zombie but recently I have had some really bad episodes and have been taking a good bit of pain meds.
Wishing you well and God Bless,
