I was wondering what does a chiropodist do to treat an ingrown toenail?

It depends... Some ingrown toenail removal procedures are performed without numbing the toe, but often, anesthesia is necessary. Your physician may use a cold spray to minimize the discomfort from the injection. The discomfort experienced from the injection will depend on your pain tolerance and the presence and severity of the infection if present. Following the injection, the procedure should be painless.
