Hi,
How are you?
These symptoms could be due to a pinched nerve as mentioned or can also be due to peripheral neuropathy due to diabetes or B12 deficiency. Other possibilities include bad neck posture while sitting; sleep deprivation, excessive fatigue and anxiety.
Please relax and do some neck exercises and take a multivitamin supplement. Take care!
It may be a pinched nerve. I have had that and my gosh the pain. It will eventually go away, put if not I would go get it checked it.
