Beelieve that it works, especially if it producing a cortisone or similar type compound. Cortisone shots are pretty standard practice in sports medicine for damaged and aching joints. Long term use does more harm than good, but I don't know how that translates to what John is doing.
Yes, it has side effects in the long term, but cortisone blends are the cats ass for getting a guy right back in the fight. I had them done on my knees several times, in order to make it thru the season, and recently I have had 2 rounds for my discs in my back.
