FAQ about Electromyography (EMG)

Is an EMG test painful?

Electromyography is a medical procedure for accurate diagnosis of a myriad of diseases that affect the peripheral nervous system or patient’s muscles. Due to the fact that for evaluation of the muscle health and whether there are some troubles with their function, the skin of a person will be pricked with the needles, for some people who undergo such type of medical examination, a procedure may cause mild discomfort and unpleasant sensations.
