“I suggest taking some anti-inflammatories, such as Aleve or Advil, if you dont have it handy, then aspirin, and see how you feel in the morning. “
No to the aspirin. There may be some swelling in the back joint and some bleeding too. Aspirin will make the bleeding worse.
And if you have to have surgery you will have to wait 3 days to get the aspirin out of your system.
Prayers for trussell. I hope you've seen another doctor by now.
