Hi
Have you seen a doctor yet? I am not a medical person but have had Shingles, it usually starts on the trunk of the body. If you shave your underarms, use deodorants it is nice to keep clean but things in the products or even shaving can upset sensitive skin. Best to get it checked out, hope you get some treatment soon.
