Train quite a bit and recover pretty well for the most part but recently I have noticed that when I jump up and land, I have intense pain in my quads that literally stops me from doing anything else for about 10 seconds. I might be playing catch with my son or something like that and an errant throw that requires me to jump up high usually has me in pain when I come down to the ground? This is 100 percent muscle pain, not joint pain and I'm not on any fad diets.

Insight as to what's going on/how to remedy things would be greatly appreciated.

Cheers.
