Hi! I also had a soft tissue knee injury that would not properly heal after someone overextended it laterally during Judo practice. I found that in the beginning month or so most of the pain was just due to inflammation and swelling, which I could control with cold packs, however once that had subsided and the pain became a deep low ache during use, the issue had became more trying to heal while still walking and running. I had a lot of advice for physical therapy and deep tissue massages, which helped, and both surprisingly in the same way, they both improve circulation to the area, more blood-flow means more nutrients in the area, more nutrients means you can heal faster. Once I learned that I started looking around to see if there were blood flow stimulation devices sold, and there actually are several kinds out there. I ended up settling on trying one of the King Brand Healthcare products because they are FDA registered, and I would have to say it genuinely helps. I heal about 25% faster when I use it, i.e. something that would take 10 days to recover from now takes about 7, and as I am getting older and heal more slowly, I think I was re-damaging my knee as fast as it could heal by walking on it, and ended up kicking the can down the road rather than actually getting better. Once the rate of healing was improved in my knee, I finally fully recovered and got back to the point of being pain free and having a full range of motion again. If you don't have the time or money for physical therapy, I would recommend trying something like that out, you can strap it on before you go to bed and the wrap helps keep you from bending it too much in your sleep.
