There is a significant lack of understanding among doctors (and the public in general) about opioids and pain medication, and it is saddening and detrimental to lives of those who truly need it. I apologize that you have to face this stigma. It is a crisis that is not being acknowledged and its affecting many people, including one of my family members who live with chronic pain and other diseases.
I respect the medical field greatly, but I have seen how the ignorance of doctors can cause damage. Keep fighting, no matter what. It is important to do research and be prepared during doctors appointments, because sometimes it can be a battle when all you are asking for is help. I hope you will be able to find some relief and care soon.
