The failure of foot skin grafting is due to the lack of foot meat, especially the instep. It takes about 1 month for skin grafting to resume walking successfully.

I think it's normal for you to say that western medicine can't be cured for two months. Even young people can't just apply medicine for two months after burns (degree 3). Burns and cuts are completely different. The burn area is large, and the meat in this area is dead, and the recovery is very slow.

So all this, coupled with the lack of qi and blood in the elderly, leads to slow healing.

My advice to you is to find a professional hospital to treat burns. Skin grafting needs anesthesia, even general anesthesia, so be careful.
