Ingrown toenails are a common problem which can be very painful and chronic if left untreated and result in a secondary bacterial infection, causing it to be puffy red and swollen. It can be due to a variety of causes including nail shape and poor toenail cutting technique.
For some patients this can be simply removing the nail portion of the nail that is digging in and can be usually be done quickly and relatively painlessly in a general visit. Often relief is immediate and with the right advice can sometimes be resolved permanently.
For ingrown toenails which are chronic or due to nail shape this might require regular visits to maintain nail shape or a permanent solution of nail-surgery can be discussed with your podiatrist.
