Last week, I got pulled from a sitting position by my dog at the vet, and went flying to the ground, I must have hit my right knee first. It started to swell, and hurt. Well, I iced it that night and not able to ice for 2 days (worked both my jobs) and iced it the 4th day. It seemed like it was getting a little better, and then yesterday it started to sting really bad (on the middle part of the leg down to the ankle) The knee feels very tight when I bend it, but the swelling has gone down quite a bit. I also have swelling and bruising on the side of my foot. I did injure that same leg/foot twice. A bad car accident over 6 years ago that caused nerve damage just below the knee, and my foot, I tripped over something in the garage (may have sprained it, but never went to doctor), but every time I work my cashiering job, the inside of my foot swells up. it will usually go away in a day or so. I haven't worked that job for the past 3 days, and the side of the foot is still swollen. Is there anything I can do at home to ease the comfort?
