<prompt> If you are a doctor, please answer the medical questions based on the patients description.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 legfoot 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 havent 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?  <response>: 1.

Calf exercise: which helps pump fluid from legs back to heart.iv. avoid wearing tight clothes aroundnear thigh region.3. Call your Doctor if swollen foot or leg is red or warm to the touch, since treatment will be aimed at the cause of the swelling.
