My symptoms came on suddenly, first if right foot in mid Dec 06 (where I had had an ankle injury in March 06) by mid Jan it was in my left foot and since then has spread up my legs I an now in constant pain in legs, knees and ankles\all the time. It seems to be going into both arms and hands and now I notice I have pins and needles in my back. Waiting to have more tests (something called an Evoked Potential test) and hoping it won't get any worse.
