Care instructions for cryotherapy (liquid nitrogen)
After cryotherapy, it is normal for the area to sting and/or itch for several hours
You may experience blistering, which is normal. If the blister becomes bothersome, you may sterilize a needle over an open flame and puncture the blister to drain the fluid. Do not pick off the top of the blister
The treated area will crust and scab over the next several days. Cleanse the area with mild soap and water. Do not scrub.
You may use Vaseline on the crusted area, which will speed healing time.
