Oh gosh, I feel so sorry for you. I know it's easier said than done, but try not to scratch. I don't know if you can get this where you live, but I highly recommend "AVeeno - Anti-Itch cream." It works very well on stopping the itch. If you can't get that, then try "Calamine Lotion." What they call the "Pink Stuff." You can get both of these at a Pharmacy.

Good luck and prayers on the way that you get some relief very soon.
