I feel so bad for you and the fact that this has been on going for quite some time. I sounds like they are not really sure what this is on your leg. My son had surgery and ended up with a real bad infection that required IV antibotics and after about 6 weeks, it cleared it up. I am just wondering if your doctor could put you on an Interveinous Antibotic? I bet this would heal it up . Be careful , sometimes oral antibotics just wont do it. Try talking to your doctor and see if he or she could try this kind of therapy. Don't wait any longer. I am hoping this will help you . You luck with your treatment.
