Hi and welcome to Healthcaremagic. Thank you for your query. I understand your concerns and I will try to help you as much as I can. Ingrown or infected toenail as in his case is common and treatment depends on severity . In this case it seems like there is severe inflammation and surgical consulting is required. Otherwise, in mild to moderate cases conservative treatment with warm water and salt soaks, antibacterial ointment. If conservative treatment of a minor ingrown toenail does not succeed or if the ingrown toenail is severe, surgical treatment may be required. It means that nail should be removed completely or partially and infected tissue should be excised. If the ingrown toenail recurs despite this treatment, destruction of the sides of the nail with chemicals or excision is done; this is known as a matrixcestomy. In every case, he should see doctor, and in the meantime, have soaks in salty warm water and have antibiotic ointments. I hope I have answered you query. If you have any further questions you can contact us in every time. Kindly regards. Wish you a good health.
