Went to the chemist today and he told me to use Pinetarsol on the inflamed area (so I now smell like really old Pine disinfectant) and he told me that I can take Claratyne wihile pregnant to help reduce the itching. So I'm going to take for the next couple of days and hope it helps. He seems to think it might be PUPPS which has been aggrevated by the hot weather on NYE - great I still have all of summer to go - hopefully these remedies help so I can get through summer without too much discomfort on the rash front, dealing with the heat will be another thing.
