This depends on the patient and the diagnosis. If you are being treated for a chronic injury or chronic pain then most experts recommend that you undergo these treatment sessions 2-3 times per week. As improvement begins to occur then the treatments may only be needed once or twice in a 2 week period.
You should expect an average of 10-15 treatments in total, if your pain is chronic in nature. Some patients with debilitating problems such as arthritis may elect to continue their laser therapy without a definite time frame to end the treatments.
Acute conditions may be resolved with as few as 1-6 laser treatments.
Daily therapy is recommended for severe pain and acute conditions. The sooner therapy is begun, the better the results will be.
