My DD turned 14 in April .... we practice pitching 1-2 x per week ... she is pitching 2 games per week.
She is playing 1st base in Middle school and pitching 1x per week for that team.
Pitching one game a week for LL. A few pracices a week but not pitching at those.
One knee is bothering her around the knee cap as well .... I think her drag leg .. right.
She just grew 3 inches in the last 4 months and lost 9 pounds ...
(surprised she can pitch at all with the drastic change we made in her form and the growth spurt!)
Doesn't hurt while pitching ... or running bases ... only occasional complaint at night (not daily pain) ... no swelling no bruising ...
We are keeping an eye on it .. little ice now and then ... occasional Ibuprofen ....
Doing some leg exercises to help strengthen the muscles (maybe the extra 3 inches requires some leg strengthening)
She has a "gun" from outfield and along with pitching she has not had pain in arm or shoulder thus far ...
Hopefully just "growing pains" for your daughter ...sounds like she has a nice future!
We are icing too...i dont think it's a growth spurt...wish it was though...no swelling or bruising either...maybe just needs some rest! I am going to take her to the Dr though to be sure there's nothing structurally.
