Knee Problem

So ever since I did my longest run two weeks ago, I have been having issues with my right knee. Whenever I sit for a long time and get up it is really tight and then when I start running it gets even worse. With race day being this weekend, I am getting nervous.

I have been icing my knee when I can and it seems to be helping, but I am considering buying a compression thing for my knee. Has anyone ran with this? Would it help and does it put any restrain on you while running?

I was looking online and found some at Dick's. There is one from Everlast that costs about $16.



I think this is definitely something to look into. Let me know what you guys think!
