I'm 17 years old and I've been waking up early hours in the morning crying with painful numb shooting pains in my left arm that goes to my fingers as well, the pain lasts for about 40 minutes and after then the numbness wears off, I'm awake now due to just experiencing this horrible pain! I've spoke to so many people about it yet none of them seem to know what it is? Does anyone here know? I don't know what else to do:(
