laser therapy has an anti-inflammatory effect as it causes vasodilation, but also because it activates the lymphatic drainage system which drains swollen areas. As a result there is a reduction in swelling caused by inflammation!
Laser therapy has a beneficial effect on nerve cells. It blocks pain transmitted by these cells to the brain which decreases nerve sensitivity. Also due to the decreased inflammation (see above), there is less edema and less pain. Another pain blocking mechanism involves the production of high levels on pain blocking chemicals such as endorphins and enkephalins from the brain and adrenal gland.
Net effect results in feeling much better and rapid healing of damaged tissue!!
