Fell on ice hurt lower back. Year later fell down stairs hurt same area. Could this be cause of leg weak, feet inflammed and red after walking??

Maybe - need more in. We would need to have a lot more information. The foot problem may not be related to the fall but you need to see your physician, get an evalaution. This can be a vascular problem in the legs. Did the fall cause weakness? Is there neurological injury? This is what we need to knw.
