Hi--
sorry to hear of your struggles--but glad it is not tooooo bad. I am one of those "in limbo folks." Tho it's been mentioned off a on for years--no deffinite dx--yet. I guess for me thats just as well--b/c I don't tolerate meds well and figure that most treatments for this are symptomatic so--"if it aint written on the final (tah dah) dx---there's still a chance I aint got it.." (just call me queen of d'nial...lol)
I've had a few mri's over the years (not easy with claustrophopia--poor techs!

) but you mentioned an lp and bloodwork. Did not have lp--neuro didnt want one I figure b/c my symptoms were not acute then: but I have asked if there was bloodwork that would prove or disprove dx of ms---all dr's said no. So if you would share--what blood tests did you get done?
thanks sharing your story...
<<<hugs>>
