"i was diagnosed with urethral stricture a couple years ago that was so bad i couldn&#039;t urinate hardly at all. i developed a bad infection that spread to my intestines and blood. i was in so much pain i was screaming. the doc at the hospital put me on 3 mg of dilaudid every 4 hrs. the next day i told him that was not quite lasting 4 hrs. he put me on a pain control pump that gave .5mg every 10 min. plus i was still getting the 3mg every 4 hrs. this finally work amazingly well but in looking at the amount i wad actually getting it&#039;s no wonder. i didn&#039;t always hit the button every 10 min. but the nurse said i was still averaging 9-10mg every 4 hrs."
