sorry for your knee issues. I agree with the advice of Shoapie and in addition you could apply arnica (gel or cream) as it has always been helpful to alleviate pain and help speed up healing for me and others I know.
Clinic called. No sign of tears, but LOTS of swelling. Keep the crutches longer and really rest, which I thought I was doing. Wants to see me in the clinic for a cortisone shot when I can get it scheduled. Guess the downstairs a bit longer for me. Knee issues stink!!!
