Suggest Treatment For Swelling And Pain In Knee

I have been having pain in my right knee for almost a week now. It feels swollen, but doesn't look swollen. I have tried advil and alleve, neither one seem to help. I am a running and was injuried in Feb. during my half marathon. I had a slight tear in my upper hamstring with the pain going into the piriformis. I took time off from running and got those two things taken care of. I have currently been running every other day, slowly, and only increasing my time very slowly. I am no where near the level I was at back in Feb. Any thoughts on what I should do with my current knee pain? It didn't really bother me on my run yesterday.....only seems to hurt when I am sitting, standing, and walking.
