Edema
"If you take triamterene and have leg pain consider it could be the medicine. My mother took it and had severe leg pain, shooting down from the hip. As she has arthritis doctors said it was arthritis and it got so bad she considered having hip replacement surgery. I saw that it got worse when she took the medicine. She asked the doctor to give her another medicine for the blood pressure and after a week the pain was gone completely - no need for surgery. The medicine helped the blood pressure but the pain in her leg was too much, as she could hardly walk. If you are taking the medicine and have leg pain shooting down the leg talk to your doctor about getting another medicine. "
