Re: what to do if your toenail is removed and does not grow back
First of all, you need to remove the bandaid and not use them anymore. Constantly wearing a bandaid allows the skin to remain 'wet' which will not allow it to heal. You need to allow the skin to dry out because right now, it is mascerated. Masceration will not allow healing. If you MUST wear a covering, wear a small piece of gauze and tie it onto the toe. Gause will allow the moisture to evaporate and bandaids will not. Apply a drop of peroxide to the skin twice a day for about a week to aid in drying it out and to help prevent infection.
Whenever a nail is removed and acid applied to the root, it can completely kill the root and no nail will ever grow again. Since it has been 5 months and you do not see any emergence of nail plate, I believe he killed the entire root.
