I have been suffering from sinusitis for months now my GP has tried everything to clear it no relief. I went back to my urologist and she told me it was the Flomax and prescribed me Rapaflo. I am concerned with Rapaflo also because it causes ED 23% of men between 50 and 60 will experience this. 0% in 1-6 months has reversed ED after stopping use.0% from 6-12 months have reversed after stopping 100% have not yet reversed after stoppage.
