Hi,
I went hiking two weeks ago and scratched my forearm and shin. It started itching a few days after (did not pay attention to that, since I thought it is just healing). But the itching did not go away and now I have some red bulges on the hand. It is worse on the hand than the leg - maybe it is because i scratched it more than the leg, however the leg is itchy as well. In addition, I can see small, red spots developing around the hand. Here is a picture - http://postimg.org/image/jwwba06pb/
What should I do about this rash? Any help will be much appreciated.
