Pepper,
you're on the highed ibuprophen dose. If your doc doesn't want you on narcotics (your doc, not your nurse), here are some things to ask the doctor:

Switch to different NSAID - individual results very, naproxin might work better for you - it's a crapshoot what works best for any individual.

Is it ok to add tylenol to the mix - offset by 2 hours. Ask about this don't just do on your own.

You can keep a journal today and list time of day and level of pain every hours; note also when you take the ibuprophen. That should help your doctor help you manage your pain.

Re: the nurse. Organize your questions so that you sound as professional as possible. As long as she answers professionally, you shouldn't give a tinker's d--- what she thinks of you personally.
good luck!
