I developed a hematoma on my left ankle about a year ago. My Dr. said it would go away, it did not. About 4 months ago my left ankle began swelling, it was not water retention. I went to a vein specialist, they did a procedure to two veins on my left leg, the procedure did not cure the problem, my ankle is still swollen as well as my foot and has a dark color around it. My right foot has started to do the same now. They can not determined what it is and I am very stressed out over this problem.
