I voluntarily went to the hospital for substance abuse withdrawal and the ER wait was too long so I decided to leave. That medical staff held me for an entire day against my will until a doctor came and told them to let me go. I have not injuries and didn't sign anything refusing treatment. Can I sue for them for holding me against my will? The ER nurse even said that she didn't know why they were holding me because nothing was in my records to say I wasn't competent and should have been released. I wasn't injured by them holding me, but I called the police and they have a report of it. What is the next step? a lawyer or not?
