its back..

I've had knee problems since high-school and after the therapy was over it still killed. The only thing that made it better was riding a bike. Its good exersize and can be fun, at one point I was doing 20+ miles a day. I don't know whats wrong with your knee, but I have a partially torn MCL and a completely torn ACL, and my body reminds me of it every time there is a major change in weather(like right now). Good luck and go to the doctor if it gets too bad.

Knee problems since high school also. Tore meniscus in college, had it repaired; tore it again, repaired again. It tore 3rd time about 12 years ago. Went to Physical therapy, got into biking and strengthened the ligaments and muscles all around. Have some discomfort at times but Aleve and icing help greatly. If you can, see about getting an MRI to assess what damage there is and what best course of treatment might be. My ortho doc is a big proponent of "RICE = rest, ice, compression, elevation".

None of us are doctors (at least so far). None of us are even chiropractors. You're too young to play around with this, as it could affect you the rest of your life. Go get advice from a professional.

with crash in using a bicycle to not be weight bearing on your way to school.... and if your carrying a heavy load of books ..you need to stop doing that as well... what i did ....was to have two sets of books
1 @ school and one set @ home ..so all's i had to carry were my notes.
i forgot to mention thermal care knee wraps that you can buy at your local pharmacy for temporary relief... with heat.
