My knee will start hurting randomly, after walking a lot, and after doing sports or exercising. it also hurts if i am sleeping in a very cold place and sometimes when it is raining (the rain hurt happens very un-often.) my knee gets swollen and i usually have to raise it up, ice it, or even take a pain killer. My knees also crack sometimes when i bend down.
Can anyone tell me what is wrong with my knees or give me a site that can help me???
