greetings friend, this can be a condition called thoracic outlet syndrome
or can be compression of I nerve
from her neck because of your neck position. I would try to adjust your fill out so that your neck is at a different angle to see if your symptoms persist. You are probably worn out and tired because he was not getting adequate sleep because of the hypersensitivity
to your underlying condition. This is not a life-threatening or worrisome condition in most cases, so if adjusting your neck angle does not improve things I would consult a physician. Cheers.
