A Little Background... I Have Arthritis, Diabetes And Have Had

a little background... i have arthritis, diabetes and have had a bypass, all which have made my legs swollen for a number of years. I wear compression stockings to help this problem. today, i dropped an exacto knife and it nicked the inside of my ankle, just below the bone. No problem, it stopped bleeding in a reasonable amt of time. Shortly thereafter i felt liquid under my heel and no apparent cut or break in the skin. I have hd my foot on paper towels for a couple of hours and have completely soaked 4 paper towels, as well as medical dressing pad. The liquid is clear, no apparent odor. I'm not really sure what is going on here.
