I was just on vacation in Florida last week and developed several small bumps on the front my left thigh. It first felt like razor burn and the the bumps appeared a few days later. I stopped in Georgia and the bumps also had welts, and very painful to touch. Now I am back home in West Virginia and along with the bumps and welts there are small blisters. I am back in my office today and just noticed it looks like there is some bruising between the welt patches. I'm treating with calamine lotion but it is difficult when you have pants covering the area. Should I go to the doctors office or try something else?
