Hi, Yesterday, all of a sudden when I was doing something, (tying a ribbon) and my entire left hand went numb. It felt heavy and when tested with a pin I felt nothing. It subsided in about 10 minutes, slight tingling as it resolved, No color change or enlargement or change of appearance. No feeling when the fingernails were pressed fairly hard. I have read about conversion disorders, but I am under no undue stress. Anything else? Thanks!
