My knee hurts i can not bend it without pain what did i do?should i use crutches!

First, stop running in P.E.; you could really permanently hurt yourself if you further injure the knees.

My knees are permanently injured (not from softball, but I WAS a catcher!!) it was from distance running.

I'm thinking from keeping in that bent position for so long during games, it may have pulled some serious muscle.

I would go to the doctor to get x-rays of both knees (to compare) and have them write you a note not to do any physical activity (except whatever will not affect your knees); but definitely stop running on them.

I'm guessing you do, but before games, would you do at least 20-30 minutes of stretching? Especially being a catcher on your knees like that, it would, like for any position, actually, be crucial to keep your bones and muscles healthy.

You need to give more information. For instance, swollen, red, hot, fevers? You need an orthopedist YESTERDAY.

If no fever, etc, it is probably not an INFECTION. You still need an orthopedist.

You don't need a neurologist, you don't need calcium, you sure as hell do not need to be asking on YA, you need to get to a bone/joint/tendon doc : orthopedic surgeon.

[you do not need a website either]

Good job getting to the doc. Good judgment on your moms part, too, listening to you.

I feel your pain, I have bad knees also wasn't nothing i did, it seem to run in my family, ask around in your family and see who had bad knees, it turned out it was my grandfather..

see a neurologist.

how old are you? are you a girl or a boy..you have to take more calcium..
