A member asked:

I feel my leg and arm weak interly but externly its working but soonly tiered. its happen sometime in left limb and sometime in right .mri ok.why its?

A doctor has provided 1 answer

Needs further eval: Many potential causes for arm/leg weakness. I assume you had MRI of the brain. Careful neuro exam needed, potentially MRI of cervical spine, EMG/NCV to assess muscle/nerve disorders, full laboratory panel of blood work and tests such as Lyme might be appropriate. Brain MRI only looks for some potential causes. The neuro exam is really important, and will direct the rest of the work-up.Good luck.
