Nerve Conductor Test and EMG for Sensory Damage

Posted By Kim on October 13, 1998 at 23:33:53:







I had a Nerve Conductor test that showed Sensory damage.  My Doctor called it patchy because I have it in many places.  If it is pure sensory do I have to do a EMG test? Can that be harmful or risky? what information will that give that the Nerve Conductor test did not?
Is it safe to give repeated nerve Conductor tests.  My doctor wants to do another and just did one last month?
Can you also tell me if your B12 is low but in normal range if it could cause a sensory neuropathy.
Many thanks.,
