With Sciatica, there’s some definite warning signs that you should seek almost immediate attention. One of those is, is if you have a neurologic deficit. That’s sort of a funny term, but what that really means is if you have a weak leg or weak legs. You shouldn’t have a weak leg or legs. It needs to be attended to. If you have a blue toe or a toe or a foot that looks like that, it is model that it doesn’t look right, doesn’t look like it’s getting blood flow to it. Also, if you can’t get around and you previously weren’t on a walker and having troubles, and now you are, you have to use a walker or crutches. You need to be seen and evaluated.
