Do I have a case?

I was a patient in the hospital. After coming out of surgery from having a lobectomy and thoracotomy I called for help using the bathroom. After being refused by a nurse, a CNA came in. I asked for a bedside commode because the tubing to my chest tube connected to wall suction was not long enough to reach the bathroom. She refuses to get the commode and insists I try to get to the bathroom. Sure enough, the tubing was not long enough. She disconnects the tubing from the wall, lets it drag on the floor and then hangs the cannister that collects the fluids, on the IV pole. Instantly I felt pain in my chest and became very dizzy. As a result, I had a new pneumothorax (which the surgery was supposed to prevent), was introduced to infection, had numerous additional chest x-rays hourly, and had to stay an additional 2 days. The surgeon told me that she may have destroyed what he had done in surgery. I filed a complaint against the hospital.
