Liquid nitrogen treats warts by freezing them. It is a common treatment and usually needs no special follow up care.

You may notice:

  • Irritation or redness
  • Swelling or blisters
  • Some mild pain

The wart might:

  • Go red or black
  • Scab or blister
  • Drop off
  • Leave a mild scar

You should:

  • Keep the skin clean and dry
  • Wash your groin with salt water, not soap, shower gels or antiseptics
  • Don't pick at any scabs
  • Leave any blisters to heal - don't pop them

If you have been given some wart treatment cream to use at home, please follow the instructions given and do not start to apply if the skin is blistered, broken or painful. Wait until the skin is healed.

Most people have no problems following liquid nitrogen treatment. However, if you have any: 

  • Fever
  • Continuous bleeding
  • Bad smelling or yellow liquid from any scabbed area or continuing pain
