Hi,Dear,Welcome with your query to HCM.
Studied your query in full depth of its details.Reviewed it in context of your health concerns.
Based On the facts,Varicose Veins
with Incompetent Valves of the left leg,seems to be your suffering,though your Doppler is negative for DVT.This appears to be early venous insufficiency
Other causes of the Cardiac failure / or Lymphatic system
failure needs to be ruled out by Surgeon / Vascualr Surgeon.
USG/Lymphangiography with Blood Tests for Microfilaria
and other causes need to be ruled out in your case.
You need to check with the Physician and Surgeon by physical check up and by lab and xray tests.
This reply would help you to plan further treatment soon with your treating doctors.Best of Luck and early recovery.
Welcome any further query in this regard,which would be replied in next
