Hi I am 21 years old, I have a tingling sensation mainly in left arm just like I am getting my blood pressure checked, warm cool feeling in forearm . First came to my attention last 2 weeks if I sleep in my normal every night position I wake up multiple times a night because my arm has completely fallen asleep. Now during the day I have this slight feeling, not as strong of course as when I sleep and put pressure on it, definitely becoming a little more noticeable as days pass, I recently moved to china this is why I haven t stopped in a clinic for a normal check-up, Thanks
