benign prostatic hyperplasia
"I have been taking Flomax for a month for Benign Prostatic Hyperplasia. I had been getting up to urinate 2 or 3 times a night, suffering from severe pain during urination. Since starting Flomax I have found  myself dizzy if getting up quickly, blurred vision, decreased sex drive with abnormal ejaculate. I have lower back pain. I feel weaker and tired all the time. On the up side I can go all night with no need to get up to urinate and the pain while urinating is 50 percent less."
