Can I sue for negligence involving a broken foot?

On 1/25 I slipped and fell in the snow, in a treatment facility, that was not salted or sanded. The following day, 1/26, I went to the hospital and found out I had broken the base of my first metatarsal. I was given a soft cast and shoe to be worn at all times. In my discharge paperwork, it explained that I need to be off of my foot for the time being. The staff at the treatment facility forced me to walk upstairs, to get my medication, as well as walk around from building to building to attend groups. Completely disregarding the wishes of the hospital.
