Is It Normal To Experience Shocking Sensation In Hands After Playing Electric Guitar?
Check how strong is his grip.
Detailed Answer:
Hi,
At this point of time, ask him to squeeze your finger while you try pulling it through. If he is able to have a strong grip, then it indicates he has no weakness. And if there is no weakness and he has no pain, then I feel there is no real reason to be worried.
At times due to overuse and other physiological parameters, the nerves may get fired up leading to paraesthesia (sensation of shock). In most cases, things get better over a period of time. You can start him on vitamin b12 supplements that you get over the counter.
I will refer him to the nearest doctor if the troubles get worse or if it persists for more than a day.
Keeping him relaxed with extra fluids.
Hope I answered your question. Let me know if you need clarifications.
