I am 53 Year female, I have varicose veins in both legs. In July 2016 I got laser operation done in my right leg and till August 2018, everything was fine and legs were healthy. But suddenly there is swelling which is not going even after taking Daflon 1000 mg tabs and there is large black as well as red blood clotted patches in my both lower limbs and pain all over the area described. Sometimes, there is burning sensation from within and itching all over the rashes. I am keeping leg elevated during sleep and resting time. Kindly suggest me how to go ahead with medications and treatment for this problem. I am unable to walk, keep my legs on the floor or even wear footwear.
