What are your damages? I would say you don't have any. The only attorney you could get to take that case will be a very shady operator.

I would write a letter to the hospital regarding the callus treatment by the NP in the ER, unprofessional and not acceptable anywhere I have ever been on staff. Perhaps ask for a portion of the bill to be forgiven, no way do they agree to forgive it all, no justification for that. If the NP had said okay and done what you suggested and then there was a problem, that absolutely would be malpractice and actionable.

Ovarian cyst may rupture on its own. My wife has issues with that. I would encourage you to be extremely circumspect about surgery for an ovarian cyst.
