Flomax and constipation

My Urologist prescibed this drug for me after having kidney stones removed, he also said I had a slightly increased prostate.
The side effects of this drug are horrendous. I've had dizzines, sore throat, running nose, constipation, insomnia and by far the worst of all is the itching. I have scratched until I have drawn blood. Anti-histamines give no relief. The only way I have obtained some relief from the itching is by holding ice cubes to it. I will never take this drug again no matter what!

Floomax should not be used by anyone. It attacks the eyes. One would never want anything ever to hurt the eyes. One will never be able to have cataracts removed, either. I took one pill, before I knew this, and yet some side effects keep increasing for one week now. I guess my liver is not very good, I'm age 64. Without a healthy enough liver, this stuff might remain in blood forever. I don't know what is going to happen. Some side effects which are increasing even though I took only one pill: unusual and severe back pain, constipation, sensitivity to light, blurrier vision, headache. Other side effects which remain but are not increasing are insomnia, at best now I have restless inferior pieces of sleep with somewhat changed dreams, not restful sleep, a completely different sleeping pattern and experience, also a few nasal things remain but are not getting worse. Over-all am morbidly affected by this change in my health this last week, especially distressed I guess by changes in vision, at least some of which and maybe all are permanent, and in the sudden lack of hope for removing cataracts in the future. My sense of self is of course changed and the knowledge of my lack of sufficient thoroughness in checking this drug out, recklessness in using, doesn't help either, but the main thing is simply being less healthy.
