Marvin Girnoff answered 8/14/2011 I Have A Lot Of Swelling And Puffiness Under My Right Eye, What Could Be Causing This? High BP, swelling under eyes (Edema) and swollen ankles are all symptoms of low or impaired kidney function. Have a 24 hr urinalysis and a CBC (Complete Blood Count) done by your doctor to find out the cause of these symptoms.
