Hello. What would you guys recommend for someone who has had a car accident some years ago (about 3)? Here are the details: She broke her two legs and one was badly injured so she had to take skin transplants (skin graft) for one of her legs and buttocks to the more injure leg. She now says the transplants have sort of "healed" but she usually has pain in both legs and her legs get swollen even with less than normal physical activity. What supplements specific to her condition would you guys recommend? I am thinking on the lines of msm and bone broths. Thanks a lot for the advice.
