I'm having one of these test done Wed, on my right hand..I heard different things..on internet..some..it didn't bother..some said..it hurt like $%#(*..Neurologist doing it..probing my hand for what's causing the tinglin..(5 weeks now) Off and on pain .between wrist and elbow. I don't think it is carpal tunnel...Wrist brace helps some... but, I'm sure it came from too much computer on hard wood.(edge of computer table)....Other than surgery..what can be done to help?I know, stay off computer )..Bonnie
