My skin itches then stings when I am around ink, certain dyes, certain furniture or fabrics, most cleaners, perfume, most toiletries and almost any chemical. If I continue to be exposed to one of these things, my joints will start to hurt. It takes days for my skin to stop singing after exposure. I have worked out and eaten healthier than most people I know all of my adult life. I am in good shape. Muscular and lean. Most people think I look younger than I am. I have run two marathon. The last in 2005. It seems like so where in the last few years, it became difficult to run. I get tired easily. My tongue gets sore if I eat very much sugar. Even from fruit. I have taken my blood pressure a few times in the last few months and it has been around 140/ I can t remember . But it was always perfect . I don t know what could be wrong.
