Hi, for what it is worth my neurologist has order an MRI for me and he said that i had "brisk" ie hyperactive reflexes and this was one of the reasons he wants an an MRI. As well as the neuropathy in my feet I have had pins and needles/creepy crawly feelings in both legs and bladder problems (I have posted about this before) I have an almost constant and a vibrating feeling in my sit down area which at one point extended up into my tummy. The brisk reflexes were one, but not the only reason, he wants an MRI as this could indicate central nervous system issues, in my case he thinks I may have something called transverse myelitits (LoL).
