• When did your blisters start?
  • Did your blisters begin after an injury, such as a burn or cold injury or an insect or spider bite?

  • Did you come in contact with something in the environment, such as poison ivy, oak, or sumac, before the blisters appeared?
  • Did any chemicals come in contact with your skin? Chemicals include soap, laundry detergent, lotion, cosmetics, or nonprescription medicines.
• Have you had these blisters before? If so, were they diagnosed by your doctor? Did you have any treatment?
• Do your blisters itch or hurt?
• What prescription or nonprescription medicines are you taking? Are you using any ointments or salves?
