Your diagnosis sounds very similar to mine, including the hysterectomy. So sorry my friend for all of the pain you have been and are going through. It’s really agonizing - I understand.

If I were you I would emphasis to your doctor that your goal is to follow their advice. But if you can’t treat your high pain flares you are worried you can’t perform your job. Don’t be afraid to stress how the pain is affecting your quality of life and job/survival. Also ask them if they can recommend or advocate for other treatments like medical marijuana (this is basically saving my life right now from having to go on disability for chronic back pain).

Good luck and feel better.
