Hello, I had prostate cancer surgery May 2013. For the rest of that year I was using a vaccum pump for rehabilitation,along with Cialis. My insurance changed in 2014 and ? It didn t cover Cialis and I wasn t able to afford it. Now at the begining of this year I was able to change insurance and am able to cover the prescription. My question is this. Without the use of Cialis I have been unable to really achieve a funtional erection. I am worried that possible plaque has build up. Will the resumption of the usage of Cialis reverse this buildup that I think is causing this problem?
