I have some plantar wart and I believe this is caused by HPV virus. Since it s a virus, I believe it would still embedded in my DNA until it dies out, but a wart at different location may occur. as I don t want to spread it to my wife... Also, I had the Liquid Nitrogen treatment on the plantar wart and now I have a really bad blister filled with liquid and blood . It is really painful due to the pressure build up, I have tried to puncture it with sterilized needle to relieve the pain but it manages to block up again and the liquid started to build up again...What can I do? I can feel the pain up to my knee and disturb my daily activities significantly.
