I have large localized red itchy raised welts (4 quarter size under right buttock and 1/2 dollar size and one penny size next to it on right side buttock.) Thought I was bitten by mosquito on the way home from the gym(wearing shorts and T) but got home and found the welts. They itch very bad. I have checked for bedbugs...(no one has been sleeping in my bed but me, no hotel visits) I had one on the back of my thigh about a week ago,when I came from a friends house... but it went away...thought it was also a bite of some kind...any ideas WOULD BE GREATLY APPRECIATED. I have no health ins. and don't really want to go to the emergency room....HELP I could send pic if that would help anyone...
