Hi I have had a nerve conduction study done on my right arm. It showed significant carpal tunnel syndrome and at the time of the procedure I had absolutely no problems. However, by the end of the day I developed right shoulder pain which through the night became so strong I was unable to lift my arm the next morning. I could not dress up or brush my teeth, I could not do my hair let alone anything else. It took me three days to settle down. Is it possible this was a side effect of the procedure or not? Thank you kindly for your answer.
