Jut an FYI...been dealing with a deltoid muscle injury past six monthes, muscle tendon tugged off the bone, went through all the usual...had an ortho endorse Cold Laser Therapy, which reduces inflammatoi while stimulating cell regeneration. Whereas CLP is very common in Europe, not so much here in the US. Anyhoo, half dozen 20 min treatments in, at $40 per, definite improvement on the injury. Carrying any lingering muscle injuries, might want to check it out.
