It was a surface EMG done by a physical therapist. There were no needles. I can touch my arm okay but I dread anyone else. I am okay with heat just not cold, I don't even like drinks cold or with ice anymore. I, too, won't even open the freezer. Showing and training my dogs has been my fun until this mess. I can pet them but if they lick my arm it's such a horrible feeling. That really tears me up. My kids are afraid to hug me. My pm Dr is on vacation, I see him next wk. What is a sensitivity test??
