I had an emg done on both legs and feet about a month ago. It wasnt that bad really. I had a great doctor that talked to me about all kinds of stuff and let me know when he was going to give me the shock. Its sort of like, that hit in the shin they do to check your reflex's. It doesnt feel good, but the pain is gone immediately so its not that bad. The only part I really didnt like was the needles in my feet. When he stuck my foot it did hurt really bad, but I have a rare form of psoriasis on my feet and hands so Im far more sensitive and he didnt do the other foot due to the one hurting. But after it was done and I walked out of the office I couldnt tell I had anything done to me at all so its a no sweat thing.
