Ranitidine has been used for decades even by doctors themselves and by there families too, without any such known side effects. This evidence has been come into knowledge just a few months back and still a lot of Doctors are unaware of this. But since this discovery ranitidine has been largely removed from the market. So this is not actually Doctor's fault.  Also this side effect occurs after years of usage. So nothing to worry. But u should not take it further.
