I have suddenly gotten edema in my back, abdomen, thighs, calves, ankles. What is really weird is the swelling in my back and hips!  I have kidney disease. It was 26% one year ago, then improved to 36% this past may and the end of November improved to 40%. Im worried this may have something to do with kidneys but I have other illnesses such as diabetes, hypothyroidism, orthostatic hypotension etc. I have tried drinking lots of water, drank prune juice, taken a prescription water pill.  This came on suddenly in the past 5 days. HELP!
Hiconsult a nephrologist and get GFR and creatinine tests. For treatment freusomide twice a day and restriction of fluids up to 1.5 liters only in a day. Get serum Na, K, CL, and bicarbonate levels done. Also blood sugar levels. Uncontrolled diabetes can also lead to kidney damage. For hypothyroidism Elton is prescribed-consult your physician and get thyroid profile test,T3, T4,TSH levels. Hypothyroid can also cause more swelling on body Best Wishes,
