Hi Tanner,
Welcome.
Sorry you have this problem.
Sometimes I loose feeling in my hands where my rsd is. Especially in the morning. Maybe your rsd is interferring with the current because of the inflammation caused by it. I think thats why I have numbing sometimes in my hands.
And they put ice on me at pt after sessions before heating pad for quite sometime. That was a big mistake.
Caused more numbness for me and hurt more and more as time went on. I finally saw on website that ice was bad and told them to stop.
Maybe your dr can prescribe meds for you for nerve problems and pain. PM doctors are great for this. They are very helpful as well as neurologists. I hope you feel better and soon. And yes, exercise as much as you can without overdoing it. Take care.
