Hi Madam, I have gone through your history and do empathize with your sufferings. Swelling on feet during pregnancy may be mainly due to: 1. Anaemia and hypoproteinimia; i.e. low haemoglobin and low proteins 2. Heart problem 3. Urinary infection 4. High blood pressure 5. Varicose veins of the legs 6. Deep vein thrombosis of legs 7. Diabetes 8. No cause. This is most common cause, however does not cause such an enormous oedema. The extent of your oedema is so much that prima facae it seems due to either Varicose veins of the legs, Deep vein thrombosis of legs or Anaemia and hypoproteinimia. Since your scan has ruled out deep vein thrombosis of the legs, we have to think of the other causes. You have been given DVT socks for varicose veins. If it is not giving you relief, please get the blood pressure checked. Also estimation of haemoglobin and proteins in the blood would guide you to some extent. The symptom of feeling of pins & needles in the leg is more suggestive of either anaemia or diabetes. Get your diabetic profile also done. If anaemia and hypoproteinimia is detected, you will have to take iron and high protein diet. My first diagnosis is anaemia and hypoproteinaemia. Please get examined and if needed treated for it. Any other cause detected from the list above, may call for the specific treatment.
