The certified technician may test several nerves. These shocks cause a quick, mild, tingling feeling. This is done by applying small electrical shocks to the nerve and recording how the nerve works. Nerve conduction studies show how well the body’s electrical signals are traveling to a nerve. The physician then uses his medical knowledge to figure out what could be causing your problem. How bad is it I’ve had a nerve conduction study and that was tolerable. They called me to reschedule and I’m on the fence here. During the EMG test the physician will be able to hear and see how your muscles and nerves are working by the electrical signals made by your muscles. < Neuropathy Is an EMG (electromyography) painful Posted by wisfloj wisfloj, I canceled my EMG appointment because I was ‘chicken’. The physician tests only the muscles necessary to decide what is wrong. There may be a small amount of pain during this part of the examination. It is used once for each patient and is thrown away after the test.
