Nope i don't have a job. I'm still studying and it's summer vacation here. So i don't think this is work fatigue or injury related. And besides the pain wasn't even a real "pain" at all, not severe or agonizing pain. The sensation was quite unnoticeable defines as pressured tingling. Which kinda resolves when i get out off the bed and stand straight up.
Again, this isn't always happen to me. It happened when i am on a stressful/anxious situation regarding to my health anxiety.
