Suggest Cure For Skin Rash On The Hand

my girlfriend broke out with one round shaped impetigo-like rash the size of a quarter, and about 5 smaller different textured bumps (rash like) on her arms. 1st er dr said that the lg one was probably impetigo and the others were viral in nature (my daughter had tested pos. for mono the day before. Girlfriend wasnt tested and just given bactrim for the one lg one and told the other would run their course. within a wk the smaller bumps spread to both arms, neck, stomach then back and then buttocks and legs..some are pea sized and pink and the rest cover her body completely and are clear and look like heat rash. She is itching uncontrollably and weve tried all otc drugs and benydryl and nothing works and the rash is getting out of control. Only area not affected is her face, but i do see one or two bumps forming. next 2 er visits dr.s called it eczema/skin rash b/c they said she needed to see a dermatologist b/c they had no clue what it was. We don't have insurance to see one and need help desperately for her itching and for the rash. weve googled hundreds of rash pics. the pea sized ones are pink, scaly, and slightly raised. please help.
