If you can't get pain meds I'd try Kratom.
Start with a low dose and work your way up. If you take too much you will puke which would be awful in your current condition.
Take the right dose and it will significantly relieve the pain. I slowly took increased doses until they started to make me feel a little woozy or get cold sweats. Then I knew my personal dose is a little less than that.
I can't stress enough though - take less at first and try a little more each time.
Either eat food with it every time or take on an empty stomach every time, but don't go back and forth unless you know your proper personal dose with and without food. It matters a lot with Kratom.
All that said, do it right and it will bring more relief than anything else I've been able to legally acquire. Absolutely do not allow yourself to take it every day once the pain is manageable. Plenty of people do... But don't do that.
Good luck. No matter what - this is only temporary. You will get through it.
