It could be measles, it could be shingles, it could be an allergic reaction, it could be a lot of things. If you are concerned, go see a doctor. Try this, run a fingernail across the hairless inside of your forearm. Press down a little but not enough to scratch or break the skin. Wait a minute or two and see if you have a raised, itchy welt where you scratched. If you do it's probably an allergic reaction. The raised welt after that simple test is called dermagraphia and a pretty good sign that you are having some kind of allergic reaction.
