I am not in the medical field, just someone who has MS.

The results of your LP would make me believe it's MS - the IgG levels and o-bands are what is looked at for a positive MS LP.

When you had your MRI was it done with/without contrast and also did you have a MRI of your Cervical Spine? L'Hermittes means something is going on in the cervical spine but L'Hermittes can be caused by something other than MS.

It's also possible that your dealing with more than one problem.
