Hi. Have noticed a return since this time last year of bilateral hand and feet tingling, which took about 2-3 months to disappear when I had it before. Wondering if recent interior painting, even while wearing a respirator, and running a fan with windows open, is to blame. Had painted a few rooms also prior to last onset. Noticed that the end of my tongue was tingling also during the days I was painting, but while that has subsided, the extremity tingling has come about. Am otherwise healthy. Cannot seem to link to lack of proper nutrients, or noticed any other symptoms. Saw a neurologist last time who cleared my bloodwork and wanted to do nerve conduction study next. I declined the nerve tests, then symptoms resolved shortly thereafter. What should I make of the return of symptoms?
