My finger is numb after 6 hours of playing, especially strongly in the place of pressing to the strings. I've been playing for the third year already, this has not happened before.
Go to a neurologist, this is not a very good symptom. The nerve may be pinched or inflamed. It is better not to run such things, then it can be more expensive.
If this is so --- apparently there was a lot of * static * --- for example, they fanatically engaged in barre, without preliminary preparation. Don't pick up the guitar for a couple of weeks. Get back.
