The fact that you believe that the nurse was unprofessional, although unfortunate, does not support a lawsuit. Pretty much every profession - nursing, teaching, accounting, etc. - have people who at times act unprofessionally, unethically, or immorally. I do not see anything in her behavior though that supports your claim that you can sue OBHS Denver Health or the nurse. You brought a complaint against her, which was your recourse. The fact that you missed a class does not amount to any recognizable economic damages. You need to have economic damages and actual damages to sue. Not simply hurt feelings, humiliation, and embarrassment. You can talk to personal injury attorneys on this site. However, I doubt any of them will even consider your case. Sorry

I agree with Mr. Leroi. It's difficult to imagine how you can pursue a claim here and prevail.
In no way am I offering you legal advice, and in no way has my comment created an attorney-client relationship. You are not to rely upon my note above in any way, but insted need to sit down with counsel and share all relevant facts before receiving fully-informed legal advice. If you want to be completely sure of your rights, you must sit down with an experienced criminal defense attorney to be fully aware of your rights.
