Had my plantar wart frozen with liquid nitrogen under my heel 5weeks ago it formed a blood blister which is very dry now but shows no sign of peeling/popping. Is this normal? Once day it starts to itch or burn.

Treatment plantar wa. The whole strategy is to come as near the the cell or cells that house the wart virus. So you have to gently peel outer skin with a clean disposable razor and then put salicilicacid/ podophyllin mix on it every 2nd or 3rd day.Rest if it inflames. Carry on for 6 weeks. Re cryo 14 days.
