sorry for any repetition but i just read the initial request for info... probably too late but just throwing in a couple cents
*oven mitt hands (stocking and glove neuropathy)
*puffy hands (a feeling of swollen stiffness when the hands don't look swollen really)
*electric shocks, tingling/'carbonated' blood (mostly dt l'hermittes i'd think)
*phantom itch (an uncratchable annoyance - in my case suspected excess b9, confirmed w labwork)
*vaseline glasses (not really something we use to describe ourselves necessarily, but something we discussed once as a way to help non msers get into msers shoes a bit)
*cement legs (this only happens to me when i get my core temperature up to a certain level.. loss of nerve conductivity..?)
*jimmylegs, for that matter!! (sudden, short painless leg spasms or jumps, explained by my neurologist as perhaps an unfelt 'itch' signal getting 'stuck' in the spinal cord)
*i don't have jargon for 'hypersensitive-and-numb-at-the-same-time'
*i also don't have jargon for something similar to the ms hug but more subtle.. when you can't take a full deep breath. perhaps due to some spasticity in the diaphragm?
and of course there are a whole list of additional terms/abbreviations/acronyms we use that aren't our own vernacular... dx, sx, ataxia, spasticity, dysphagia, nystagmus, ON, peripheral neuropathy, vibration sense, position sense, large fibre modality, o-bands (oligoclonal), CNS, BBB, GI, permeability/impermeability, CSF, serum, RBC, LP, post-LP postural headache... &c &c &c...
and that's not even getting into the whole set of jargon related to CCSVI.
