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%. I'm 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!
