This thread will probably be shut down, but I'll try and respond before it is. I started pain management nearly 2 years ago. Initially, I was scripted hydrocodone, then perocet, and now I'm on Oxy 15 IRs.
I'm the same way. I hate asking for something more due to the fear of coming off as a drug-seeker. I don't see my script ever being upped from where it is now. In fact, I had an appointment with the PM doc last week and I got lectured pretty good because my random drug screen came up negative for oxy (ran out about 4-5 days early).
Like someone else stated, just be honest with your doctor. But be careful too. It's easy to start using more than you are scripted. Believe me. If you feel like the oxy 5s aren't working for you, tell your doctor that. If you say that it isn't helping with the pain, I would imagine he would try to give you a dose that would. All my opinion, of course. Like I said, be careful with the painkillers and don't lose your doc's trust.
