After being thrown from a mule at about a 20mph pace, full body weight at about 6ft height, all on my right knee, the pain is real. I have mrs johnr rub it from time to time, and use a Ben gay type pain rub on it and that does wonders. I also don't consume much for sweets, sugars, or any of that, as sugar basically I believe caused all of my mothers huge medical issues. She was a baker and ate sugar like most of us breath air.
My knee pain is constant, but livable, I really only have issue if I am on it say to work on something while kneeling, or while getting after it in the sack. If I am in an upright or sitting position its seems to be less of an issue. At my age I know its only going to get worse, as I am fairly young yet. Guessing my real issue will be on the come.
On a bad day ice and a single Aleve will take care of it.
I think guy is onto it with diet being a focus on pain management.
