oh sweetie! hugs for you. It can be so scary to have so many sx and no dx to go with it. its frustrating, and you just want someone to say you have ABC, and this is how we deal with it. It doesnt sound like your medical team has been able to do that for you, just yet.

There are more than 100 diseases that can mimic the signs and sx of MS. yes, it does sound like you have MS, but a Vit B12 def can cause the same sx. Lupus and Lyme can cause the same sx. Have they at least told you which way they are leaning with your test scores?

There have been many diagnosed without lesions, and with clean spinal taps. Make sure you report this latest event, and keep a journal. Are you feeling better today? An MS relapse is a new symptom or worsening of an old sx that lasts for at least 24 hours without a break in the symptom. If it lasts less than 24 hours, then its a flair, and indicates that you are tired, stressed, overheated, hungry, or were in a position that your body didnt like (such as on your knees to bath kids) its so important to keep a diary of how many times this sort of thing happens.

Hang in there.
