actually, pretty damn well. easiest MRI I have ever had. the EMG was just interesting. for those that don't know, the purpose of the EMG is to first and foremost determine if there is any nerve damage caused by the herniated disc. the doc sends electric pumps through your leg, which measures the responsiveness of the nerve. good news is I don't have any nerve damage. he also checked my left leg muscles, which was really cool cause he sticks needles in the muscles and you actually listen to the muscles on laptop speakers.
