Preparing for an appointment

A doctor's appointment usually isn't necessary for heat rash. If your rash is more severe, you may want to see your primary care doctor or a doctor who specializes in skin disorders (dermatologist) to be sure it's heat rash and not another skin disorder.

Before you go, it's a good idea to list questions you have about your condition. For heat rash, questions to ask your doctor include:

• What could have caused this rash?
• How can I treat it?
• Do I need to limit physical activity until the rash clears?
• How can I prevent it in the future?
