Hi guys.I woke up in the middle of the night two nights ago with my foot itching randomly. so I kept scratching it and it was red but no bumps. Then the next day the bumps were pink all over my left foot. Now they're dark red. can the hiv rash just be on your left foot and no where else on your body? its like dark red bumps only on my left foot or is it probably a bug? I don't feel sick otherwise.
