Got mama's red light hooked up in a good spot where she can use it. I said even if ya can't use it directly on your arm because of the cast, it will still have a great overall regeneration in all aspects....and put arnicare on her back....that also is a game changer.

Tell me about the red light therapy and where can I get a legit one

For a lesser or higher fiat price....same concept...and like the one mama has, you can lay it on any portion which ya can with all. SO though they sell them as back ones, knee ones, etc. a primary wrap you can lay on any portion covers it all.
