Burns can be the result of coming into contact with a "high-heat" device such as any light bulb, CHE, or spot light. The first sign of a burn is that the skin looks hard and stiff in the area of the burn. The skin will remain this way for several days. Then the skin will completely come off the burnt area, either with a shed or by movement of the boa. This will leave a RAW exposed area that often will bleed.
You should treat the burn area immediately with Polysporin, even before the skin comes off.
Clean burned area with a 50/50 hydrogen peroxide/water solution. Use a swab to clean the area.
Apply Polysporin or Neosporin to the affected area twice a day.
Consult your veterinarian as soon as possible
Sorry... copied from a care guide. Also, make sure you get a decent thermostat or dimmer for your heater. Check the heater too... may need a new one of those.
