For a week now, I’ve been suffering from knee pain. The left knee in particular. I’m not sure what’s causing it. I’m 22, jog regularly, have not been in any accident nor had any injury. I noticed that there isn’t any inflammation on my knee which leaves me clueless on what’s happening. I’m to see a doctor this week but do you have any idea on what this might be? Is it possible to get a joint pain without it getting inflamed? Could this already be osteoarthritis? It does lock up like I need to pop it up, by the way. Thanks for any help that you might give.
