### input:
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 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?

### output:

**1. Since there is present and past history of Injury thus get yourself checked with an Orthopedic and/or Sport Medicine Specialist Doctor for necessary examination and Investigation.2. Because of gravity, swelling is particularly noticeable in the lower part of the body [foot swells up] thus what can be done at home to ease comfort is/are:i. Elevate your legs above heart level while lying down ii. salt free or low salt diet: since salt causes fluid retention and swelling]iii. Calf exercise: which helps pump fluid from legs back to heart.iv. avoid wearing tight clothes around/near 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.
