Not particularly. The heat sensation triggered by the light will tend to make the brain focus on the heat sensation & less on the pain. The same can be said for lotions & creams that give you a warm or hot sensation over the joint. The underlying inflammation in the joint is not altered by such therapies, you are just distracted from the pain transiently.
