Edeam from abdomen down. Pitted edema in both legs, so severe at night I have trouble walking, does go down over night but still swelled when I wake up. Has been happening for over 3 months. Echo came back normal, and all the lab work, CT scans, ultrasounds have come back normal. I have been a diabetic for 29 years and do have peripheral neuropathy in both legs from the knees down, but that has not gotten any worse before this all started. Have been put on a dieretic, but it is not helping and am afraid of continueing to take it beacuse it may cause problems with my kidneys. Not sure what else it can be.
