Hello,

As such no major side effects are reported after nerve conduction velocity test. But you may feel a little pain or cramping during an EMG test. A tingly feeling, like a mild electric shock, during a nerve conduction study is often experienced. At the point where the needle was injected you may get an infection or bleeding.

Since now you are experiencing weakness and numbness on the left shoulder post- NCV test, you are suggested to get a follow up clinical examination done so that you can be treated for the cause at the earliest.

Take care. Hope I have answered your question. Let me know if I can assist you further.

Regards,
Dr. Nupur K., General & Family Physician
