Well I can tell you that I sprained my left ankle in April and I expected it to be better within a month too. It would seem to get better then it would swell more and be somewhat painful and then the swelling would go down again only to come back a short while later. I wouldn't worry unless you have excessive pain. My ankle still shows signs of being sprained and it's been 4 months. I went on an hour and a half walk. Shortly after the walk my ankle hurt like it did before but only for a short time and I've had no swelling for a long time. I would not rush the healing process. Allow a good amount of time for it heal and I would prop your knee up when you're on the couch and also ice it some to keep the swelling down. And take tylenol or whatever your doctor recommends every 4- 6 hours for the pain or achiness you feel. Allow yourself to get more sleep too. This will help your knee to heal faster and better.
