It depends very much on the type of injury you have. For example, sprained ligaments and tight muscles tend to respond faster to Laser Therapy, and may only take 1 or 2 treatments. Other conditions, such as one that you may have had for a very long time, or neural pain could take as long as 6 weeks before you notice any results.
The amount of time will also depend on your overall health and your own body's response to laser therapy.
One young man who came into the clinic with a mildly sprained ankle, required only 1 treatment to start the healing process and remove pain and restore functionality.
However, a retired woman with neuropathic pain resulting from a car accident 7 years ago, required 12 treatments to reduce her pain.
