I hurt my knee and I couldn't walk easily even with assistance. They did x-rays and determined it wasn't broken and said I probably (and that word is important) just sprained it and I would be fine in a couple weeks. The hospital refused to sell me crutches, and when I said I needed them to walk, they told me I could walk just fine because it wasn't broken. Several months later and I'm still not better and I've been told I probably tore a ligament and I might need surgery. Gee, maybe I wasn't being a dramatic cry baby after all???
