I am a teacher who has little red spots on arms, neck, face, shoulders, chest. I recently traveled to Mexico and began having issues; I also had bronchitis, ear infection and heavy cough that did not resolve with amoxicillin and full pack of prednisone before the trip. Three weeks later I have this scattered rash with a light itch. I am also having sweats and cold chills when I am active (this sweating is rare). Could the sweating irritate my skin? I try to wipe down with a damp cloth after each episode.
