I have had a bump on the outer edge of my right knee for about a year. My legs tend to swell when I travel to mainland. Recently, 1 week ago I bumped my leg (1/2 way between knee and ankle. Very tender even now and a noticeable bump. Barely discolored. A few days ago on the inside of my ankle it has turned color, bruise like. I have also had spider veins on the inside of my knee. This is all on my right leg.
