Unfortunately, you have made the same error that has cost many pain patients their access to pain medications.
NEVER self medicate or take more than prescribed of ANY pain medication.
I am not yelling at you, but capitalizing for emphasis- the number one reason for getting dismissed from pain management is self medicating/misuse.
Pain management is not about eliminating pain, but managing it to levels that allow you to function as much as possible, while reducing pain.
Taking more than prescribed is SELF MEDICATING- and can be lethal.
The proper steps to take when your pain meds aren’t working is to contact your prescriber and ask them what you should do. Only if they permit added doses should you take them.
This could be a bigger issue if you do need surgery, since pain management post op may be withheld or severely limited.
Your best option is to be honest, despite the potential consequences of dismissal and hope that the doctor is willing to continue to treat you.
The other issue is IF you are tested or called for a pill count and you have nothing showing-those results become part of your medical record, and can result in blacklisting- restriction on opiates from any doctor/pharmacy.
That's difficult and I too am sorry. I think being honest is your best hope. Doctors are under so much scrutiny that they do sometimes make no exceptions but all you can do is explain. I hope that they can offer some alternative suggestions for you for chronic pain. So hard to deal with! Again, very sorry.
I am sorry you are in so much pain. Use of opiates (even lesser strength ones like Codeine) cause your brain to need more and more. It is addictive but with chronic pain it is different you can switch to a more appropriate combination. . I know it is going to be hard to confront them. But it is better to talk to them before a drug screen. Do you think you have a good doctor that would listen?
