my wife (57) has had edema in her legs since april.  along with this, she has been feeling heat and a prickling sensation in various areas of her body in addition to the legs.  she has had some pain in the legs and the tingling feeling that comes and goes.
Hi Thanks for posting your query.  There are many causes for edema of leg. Common among them are Low protein levels in blood, Kidney failure, Liver problems, Heart failure, Problem in blood circulation to legs.  I advise her to get these test and revert with reports.  Serum Albumin, Creatinine, TSH.  Ultrasound Abdomen pelvis, 2D ECHO.  For her tinging feeling in her legs she needs to get tested for Diabetes and Serum vitamin B 12 levels.  Kindly revert with reports.
