Thanks for the reply, yes that does fit into my medical history, I was working as a Dental Assistant so i was constantly using my hands in repetitive motions all the time. The first EMG/NCS showed that i had severe CTS in my right hand (my dominant hand) and mild CTS in my left hand. The trigger finger developed about 2 weeks before I had the surgery. I didn't have the burning pain, swelling or the color changes until after the CTS/Trigger finger release surgery.

I'm wondering if the enlarged median nerve could be a result of the RSD or could the RSD have caused the reocurrence of CTS due to all the swelling that I have. I'm trying to make sense of it all especially since the second EMG/NCS came back negative and showed improvement when compared to the first EMG/NCS.

I searched for info regarding what would cause the enlarged median nerve and have not found too much info on it. Any other information or opinions would be greatly appreciated! Thanks!
