How long does the blisters take to heal?

[SteveWall56]

After the surgery, I saw a huge blister on the left of my lip which the doctor had told me that it was caused due to that the foreskin was attached to the gland of the penis. How long will it heal? It’s all dried up now and it looks like dried blood.
