Me and my son have all these rashes in our body, i mean everywhere...neck, chest, butt, legs...armpits. i was told it could be bedbugs, but could it it be syphils on the skin? i have had sex in different ocasions but never encountered touching any type of rashes on anyone. i dont know why all of a sudden we are itching and after itching on them ill get a burning sensation, and more at nite. please help.
