Flomax and enlarged prostate

My husband was prescribed FLOMAX about six months ago for a slightly enlarged prostate. He is 48 years old and had been very fit as a contractor in the construction industry. Now he is extremely weak, has terrible pains in his elbows and joints especially fingers. Last week he thinks he broke a rib just pushing a piece of scaffolding into place (something he has done many times with no ill effects). He has aged in his body so much that I fear he may not be able to continue work. He has no energy at all and seems irritable and depressed. I feel that by reading the side effects that others have mentioned that we have hope that he is not dying! If he stops will these side effects go away?

I took flomax once about six months ago prescribed to
treat a kidney stone and enlarged prostate. One dose
was enough to convince me that I did not like the way
I felt with this drug in my system. Slugisness, dizy,
and very odd. But the one symptom that I still have
after six months and one dose is a constant ringing
in my ears. Is this the side effect for life?
