Was leaning on my elbow, reading a magazine, and my left arm started going tingly and numb.Thought it was the ulnar nerve acting up in my left elbow, but it came on very fast.Then the feeling went down my side and left leg, then back up to my head, to where I could feel tingling on the side of my face, also had numbness or tingling feeling in my mouth and tonge which felt very odd. Is this some kind of pinched nerve in my elbow or neck,..... or stroke symptoms.I know I have an ulnar nerve issue in my left elbow, which has caused tingling and numbness in two of my fingers and the side of my hand,..... but never felt anything like this before, this went up and down my entire left side, it would fade away, then come back maybe 10 minutes later, or just my tonge would get tingly and numb for a minute or two and then go away.
