I practice PBM (photobiomodulation) in the clinic. Underneath PBM you have L.E.D. (Light Emitting Diode) and L.A.S.E.R (Light Amplification by Stimulated Emission of Radiation). Of the two of them, L.E.D. is the preferred choice because it is inexpensive (home use) yet it has great efficacy where L.A.S.E.R. is much more expensive and it has other uses. PBM is great for any type of pain and inflammation whether it's for your shoulder, knee, foot, etc., especially for broken bones. If you have pain and inflammation then LEDs is definitely one thing that can reduce it if not make it 100% better.
