Tendonitis

Ya i have really bad tendonitis flares in my wrists from climbing, after working out or climbing i always make sure to several sets of light weight reverse wrist curls and it has almost completely gone away, it was so bad before it killed to hold a frying pan... Seeing as we all know the wrist bone is connected to the knee bone, i bet if you gradually strengthen those knees, more for stamina than pure strength i bet it'll probably lessen too.

I had it pretty bad my senior year of high school from playing golf too much and it sounds similar to your situation. I know you compete in running every now and then and like to train on the tramp quite a bit in the summer, but unless you really need to keep using those muscles/tendons, it wouldn't hurt to lay off.

When mine started to get bad, I would just wrap it or use a brace before matches. Afterwards, make sure you ice it and don't exert yourself unless necessary. If the pain keeps getting worse though, I know there's some injections you can get to relieve the tension.

Also, ibprofen works well with this stuff.

I had tendonitis in my foot/big toe. The tendon that ran along the top of my foot into my big toe got really sore and inflamed. It was because my ski boots were to big and so my foot was sliding around which caused my to constantly lift my toes to stop the movement.

Unfortunatly the only way I got rid of it was to rest it. I stopped skiing and any strenous excersise for a couple weeks and iced it often as well as rubbing Neurofen and Voltaren Gel into it quite often. Basically your best bet is just to give it rest.

maybe try a squat you little fairy boy

I had the same thing under my right knee and it was also from running a lot in formation while running in the navy/treadmill, skiing and landing on flats, and hiking. They prescribed me naxopraxen which helped a ton. The doctor gave me a patella strap to wear while doing activities so I wore it all winter. I think it helped pretty well but that spot would still get sore. Check out the injury forum, there is a thread on this somewhere. Probably more than one. Probably way more helpful than me.
