Hi I m 26, 6 ft tall, and 220 pounds. I ve had asthma as a child, and am allergic to a lot of diff things. My grandmother died of cancer last year. I have a knot on the side of my left leg. Its been there for several years now. ITs soft and it doesn t hurt. Its been the same size for a long time, so I didn t really worry about it. But now I it looks like it might be getting a little bigger. Its probably quarter size, and its much more noticable and pronounced when I m standing.
