I am 40 years old, a little overweight. I have had a lot of numbness / tingling / poor circulation in my hands, and painful glands in my throat when I swallow over the last 12 - 24 hours. Otherwise, generally well, no sore throat, runny nose etc. but have not had enough sleep over the last few days. Started a new job last week that involves some heavy lifting so thinking it's associated with my back?
