Any nurses working with chronic pain

[ER-RN2]

Does anyone have any chronic pain but still work full time? How do you do it? I'm having a tough time. I work full time but it takes lots of time to recover after 12-13 hour shifts. (My job only has the option of working 12 hour shifts.) I don't mind to work my butt off but lately I'm having a really hard time getting through the day without wanting to scream and yell about how much I hurt. I have a chronic disease and I do anything and everything I'm suppose to do per my doctor's orders. I work in the ER and it is hard to see others come in over and over getting pain relief even if they aren't followed by a regular doctor. Thanks in advance for any advice you can give.
