Hello, a bunch of pimple /mosquito bite like spots have appeared on my legs, I have not gotten bit by anything, and I feel like they are spreading, it started today I think, they are very itchy but endurable, I are two burgers yesturday and I am not sure of how well they were cooked, could it be food poisoning? Also, a bunch of birthmark like small dots have appeared on most of my left arm, I haven t don t any tanning, but I did visit a swamp like area an fell in the water, had a few scratches from rusted metal/old wood, should I be worried? ( I got a tetanus shot about 3-4 years ago) Thank you very much, Iulius S.
