Armpit rash: Red rash in the armpit can be caused by allergic reaction to deodorants, yeast infection which may be itchy and is often caused by friction and sweating, or cellulitis, which is a bacterial skin infection. It would be best to have a physician examine you for diagnosis and treatment as each of these possibilities are treated differently.
