In June I had my bladder and prostate removed. I now have a swollen right leg, slightly red in color and a knawing pain leaving me unable to sleep through the night. The swollen leg is the same side as the ostomy site. I am injecting delaparin for blood clot although it is not completely definitive that I have a blood clot. Is this a known problem and what can the swelling be caused by. Don't know were to go to help - which specialty would best know the cause?
