The laser light which produces the heat is moved evenly over the nail in a grid pattern. It will take usually 2 – 4 minutes to complete the treatment to each nail. Even the healthy looking nails may get treated at the Podiatrists discretion, as microscopic colonies may be present on other nails.
Patients report a heat sensation under the nail directly underneath where the laser is passing. This builds up more as the treatment progresses. It should not be painful but if the nail becomes too hot the Podiatrist will adjust the treatment accordingly depending on your feedback.
