I went to hospital this morning at 7.20 am Friday . the front of the hospital near entrence doors on Bovaird drive was so icy I fell and hurt my knee which has ben replaced.This is not on. It is a hospital and I could have broken my leg.I am 75. I complained to security . just took my name and photo of the area. no further advice or action was taken.If my knee swells or have any problem what do I do?
