Hemorrhoids Burning Urination

rectal pain and irritation?
I am 30 yrs old and suffering from rectal pain and irritation for the last one week. I visited my doctor yesterday, after a rectal exam, he told me that there is no sign of hemorrhoid or fissures. He suspects that its my prostrate that is causing the problem and he had prescribed Ciprofloxacin and flomax and sent my urine and stool for tests. I am really confused with his prescription, because I don’t have any other symptoms related to prostratitis such as frequent urination, burning sensation etc.. any ideal on this?
Don’t take the Flomax unless you never want your little man to stand up and salute again!
