My knees have been somewhat sore for awhile. I think that I have had chronic inflammation - probably the beginnings of arthritis.
Last week I walked on cement for two long and went up and down the stairs too many times. Now I think I have acute inflammation. My knee is swollen, it is a little warm, but there's no redness, and it is painful - the nerves are acting up.
I have been resting and hope that the inflammation response is helping the cells near the damaged area to tear open and bath the injury in healing chemicals and fluid. Then my body needs to mop up the dead cells and build new cells and blood pathways. I hope it works!
