Thanks for writing your query.
After reading your post, I would like to suggest you that you should get yourself clinically examined and get following investigations done :-
2. Serum protein.
3. Urine examination (Routine/Microscopic).
4. Lipid profile
Avoid keeping your legs in low position for long. Keep pillow under your legs while lying.
Medical management can be planned according to the reports of the investigations.
I hope this is helpful to you.
