Its hard to tell without a picture! (not meaning to sound dodgy or anything!)

This could be hives if it looks more like the third in which you should get it checked out or try using prition or some other anti-allergy over the counter drug.

If it looks more like the first website then it looks like what would happen when something bites youb an you scratch it so it becomes white and raised of which i have ha before and many others!

If you are that concerened ggo get it checked out by a doctor.

If it's hives you've gotten into something you're allergic to. Naproxen did that to me, it was all over my body, very itchy and very painful. Check any medication you're taking and see the Doctor.
