Hi, About a week ago I developed a rash on both inner thighs near my groin area and today a similar looking rash developed on the skin surrounding my arm pit. The rash looks like misshaped ovals. I don t know if it is heat related or perhaps an allergic reaction to something I am eating. I am not taking any medication, am 46, male, fit and otherwise healthy. I have an appointment to see my dermatologist Tuesday. Any thoughts on what type of rash this may be or the possible cause? Thank you, Drew
