How can I kill the proud flesh of ingrown toenail?

Happy feet on sandy beach

I have an ingrown toenail but I removed the ingrown toenail. The only problem I have now is how do I kill off the proud flesh or the flesh that is coming out of the side of the toe?

In your case, the tissue is probably just swollen due to the ingrown nail and then the trauma of the subsequent removal. Keep your toe clean, use antibacterial ointment, and bandage it. Use ice also to help decrease the swelling. If after couple days your toe doesn't seem to be healing, you should see your doctor to make sure there's no infection.
