Can my daughter have MS

She has so many of the symptoms, but MRI's and Lumbar Punchure came back negative.  Her pain got better while on steroids, but is back again.  Symptoms went from head, to arms, then right leg, then left leg and now both legs.  (numbness, tingling pain, can't walk very much, is in a wheel chair in just 1 1/2 months and it has now been 3 1/2 months, her memory is really getting bad)  Her Neurologist has now referred her to another neruologist.  Can MS be this agressive and fast?
Please help.

I do not think so, Multiple Sclerosis has to show eventually and if she is experiencing those symptoms she most likely does not have it. Multple Sclerosis, like the name says, has to show at least twice on the MRIs as little birght dots or something... and if her Lumbar Puncture came normal then she doesnt have it, Im pretty sure but Im not a doctor. Have you tried LYME Disease? was this even a suggestion by the doctors?

Hi,
I am sorry to hear about your daughter . This may not be Multiple sclerosis It doesn’t get worse so soon . It has to be a problem related to nerves . Please go for an MRI of spine and discuss with the neurologist . Hope this helps you . Take care and regards !
