Bummer experience, General.
"monogrammed cuffs" *laugh* I made a pledge to myself in residency to never, ever get monogrammed cuffs.
EMG- electromyelography. He wants to check your nerve conduction, to see if it's stunned or damaged. BTW, poked on the side of your arm? That's odd. The median nerve goes down the middle of your arm, hence "median" and that's the one responsible for carpal tunnel syndrome. Was just rereading your post (and mine) and I'd say that it's doubtful it's carpal tunnel syndrome unless you got pricked right on the inside of your wrist and or/ you do a repetitive movement with your wrist. By poked and prodded and tapped, did he tap on the inside of the middle of your wrist? And did it elicit a not too pleasant shock to the thumb, index, middle, and half of your 4th finger? If so, that's a positive Tinnel sign for carpal tunnel syndrome. Wear the brace (even at night while asleep). Sometimes physical therapy helps a lot. Don't let him talk you into surgery right way.
If he tapped on the middle and didn't elicit the shock or numbness, and if he flexed both your wrists and touched them together (Phalen's sign) and didn't elicit similar symptoms, it's probably not carpal tunnel. Being poked anywhere along the median nerve can elicit radiating symptoms to the first 3 and a half fingers but wearing a brace won't help at all if it's not carpal tunnel. Carpal tunnel is due to inflammation within one of the wrist sheaths through which the median nerve passes through. The brace helps prevent further inflammation in that area.
If you got poked on the side of your arm, are the symptoms sorta similar to hitting the funny bone? If so that's the ulnar nerve and you should be feeling a radiation to the little finger and half of the 4th finger. Anways, a brace won't help that either. Hopefully, your nerve was just stunned. Called neuropraxia. Can take weeks for it to return to normal. (I've had a similar experience, volunteered for an arterial draw in the wrist and felt like a little Thor dude god of thunder was throwing his hammer down my arm every night) Sorry, long post. Hope this helps.
a Coke eh? man... I'm lucky to be able to hit the john by noon... ah well..
