My mother has stage 3 chronic kidney disease along with rheumatoid arthritis and she is swelling on her legs, feet, hands, and face is very swollen as well. She takes a water pill lasix along with predenison, tramadol, and lisinopril for her hypretention. Is it her kidneys that is causing the swelling and if so what can be done she is in pain and is hard for her to walk and get around what can we do?
