Laser devices are now used for several foot and ankle concerns, from stubborn nail fungus to pain after an injury. This guide explains in general terms what these treatments are said to do, how they work, what a session usually involves, and what to ask a podiatrist before deciding.
What conditions can benefit from laser treatment?
Two broad kinds of laser appear in foot care. The first targets nail fungus, known medically as onychomycosis. Oral and topical treatments for nail fungus can take many months and do not always work, which is why some people explore laser options. Reported timelines for laser treatment are often a few months with repeat sessions, but results vary and the evidence is mixed.
The second kind is low-level, or cold, laser therapy. It is used to ease pain, swelling and inflammation after sprains, sports injuries or surgery. It does not produce noticeable heat, and some users report relief within a few visits.
Some devices are also used to soften the look of scars. Anyone considering these treatments should ask for evidence specific to the device and the condition.
How does laser treatment work?
Laser treatment delivers light energy into tissue beneath the skin. In cold laser therapy, cells are thought to absorb the light and respond with changes that support healing and reduce pain and inflammation. In nail treatments, the light is directed at the nail and the infected tissue underneath it, with the aim of damaging the fungus.
The depth the light reaches and the effect it has depend on the wavelength and the power of the device. Research on foot-related uses is still developing.
What to expect during a laser treatment
Sessions are generally short, often under ten minutes. People are given protective eyewear. A handheld device is held against the skin or passed slowly over the area. Most people describe it as painless, perhaps with a brief feeling of warmth. There is usually no recovery time, and additional sessions may be suggested depending on the condition.
Questions worth asking a licensed podiatrist include how many sessions are expected, the total cost, whether insurance covers it, what the evidence is for this condition, and what the alternatives are, including doing nothing.
A podiatrist is also the right person to see first if a toenail has changed color or thickness, since several conditions look like fungus. Laser treatment is not a substitute for a diagnosis.
