benign prostatic hyperplasia
"2nd day on 5mg started to work with rock hard erections however experianced headache, lower bowel preassure. 3rd day erections would wake me up & hurt! Leg/ankles aches   severe lower bowel preassure like you need to go #2 but can't! Enjoyed the initial rockhard erections but not at these side effects or $230 for months supply! I'm 50 & work out 3Xs a week. Not worth side effects!"
