Pravachol prostate problems

I'm 57 years old, and I've been on Pravachol for a little over 2 weeks now. I've noticed some prostate problems. It feels like it's become enlarged; uncomfortable. I've not had any unination problems so far. When I wake up in the morning, I'm more or less fine. But the problem of feeling 'uncomfortable' in the evenings, after taking my 10MG of Proavachol, becomes more pronounced. My question: Is it likely that Pravachol is effecting my prostate?
