Hi,
As certain blood tests related to circulation came negative,
venous insufficiency or blood clot in the lower limb can be safely excluded. You have not mentioned your age / sex. Well, it can be natural
hormonal changes.
Other causes to rule out are:
- Injury or infection
- Lymphedema
-
Cirrhosis of the liver
- Kidney problem
- Being
overweight can too cause build up of fluid in the feets, legs and ankle (so although you have lost weight but haven't mentioned how much you were weighing prior to that)
Make sure to consult a medical specialist for relevant examination (heart, liver and kidney) and investigations. Till then:
- Reduce your salt intake
- Elevate your legs (above your heart)
- Avoid wearing tight clothing which hampers blood circulation
- Wear stockings or compression socks
- Make sure to move around, if sitting or standing for
prolonged periods of time
Take care. Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. Munish Sood, Ayurveda Specialist
