It's temporary. You'll get over it much better than some of the after effects of COVID that I had.

The fact you are getting a response to the shot I see as a positive thing. But if this is longer than a few days since the shot, then maybe you actually have COVID or something else.

If this is lingering something or other, then go to someone that has half a chance of figuring out what it is or at least a chance to eliminate it as being something to worry about.... your doctor!
