I have numb feet, from peripheral neuropathy. PN can come from MS, from diabetes, from Polycythemia Vera, from a stroke, from Shingles....many causes. As others said, an MS dx usually comes slowly. In my case I got an MS dx, then a Porphyria dx, and much more recently a Polycythemia Vera dx (in PV, too high numbers of platelets and red cells). So I have three things at least which can cause numb feet. I didn't get the numb feet as my first symptom, however. I had other things, weak hands, the fast pulse, the dizziness, meandering walk, etc. My symptoms at dx were eye trouble, which is usually easier to fit into an MS diagnosis.

I won't add any more comments to those already given on the inadequacies of the medical people and the work-mates. But perhaps it wasn't too vile of the chiro to ask you to look for MS? He shouldn't have said outright that you have it, however.
