Now I'm 90% sure that my problem is the osgood-schlatter disease because I have all the symptoms:
-Just in one knee
-in boys around the 16 years
-with ice the pain goes
-antiinflamatory helpe dme a lot and reduced the pain a LOT.
I investigated this days more about this disease and the solution is just leave activities that hurts me like the squats and wear a pad to reduce the pressure in my knee, also I would keep myself stretching a lot before and after the train, and finally puting ice every day in mi knee 20 minutes 2 tiemes a day.
I'm happy because I think that maybe my bones are getting bigger, and also the problem is not yo serious, now as antigravity dog says: get to practice !!!
also does anyone know if exist a relation between my 100m speed and my TJ distance to get a standar of what distance should I can LJ??
Thanks guys
