Also, if your injuries involve tendons, ligaments or cartilage, you can feed those tissues with gelatine. You can buy plain gelatine and add hot water, stir vigorously and add a little apple juice for flavor and to cool it to drinking temperature. Consume rapidly before the goo starts solidifying in the cup.

I did this daily for a year or two to help heal old injuries. My impairment improved substantially and was never so bad again.
