so i got this bug bite on my arm last week. then it turned into a rash that looks like poison ivy. now all it does it spread to random spots around my body more and more. ITCHES and burns a ton. all the meds that my doctor and the skin doc gave me helps very little. now think its just in my blood stream. word is that sometimes things like this can kill. wonderful. doesn't seem to be a cure. they say just wait it out. what the **** is that... atleast its not contagious anyone know what the hell i've got. the rashes look just like poison ivy... help?
