Nail fungal infections can begin with damage or injury to the toe itself. The infection becomes present due to the inflammation, slow healing and loss of circulation. Long term management of nail complaints requires persistence and attention. Watching for signs of infection is recommended in order to reduce the risk of further irritation, damage and potential nail loss. A toe nail provides protection against invading pathogens and if this area becomes damaged it is more susceptible to infections finding a way in. Appropriate wound management may help the toe nail to recover from the damage and in time its growth should recorrect, however if the ingrown toenail continues to cause a problem I suggest speaking to a Podiatrist who can assist you further.
