Had nerve condition test and muscle test said no nerve damage but muscle damage in l-5 back and left leg do not understand leg numb tingling months?

Test not sensitive: A nerve conduction test is not particularly sensitive when it comes to detecting nerve pain and irritation. It can be helpful to demonstrate medium to long term nerve damage, but this is not a test I routinely use for patients with nerve pain derived from the lumbar spine because it is not helpful.
