Yes to both questions. Brain lesions have many possible causes. Creepy-crawly sensations can, too. And you can have MS, even get an MS diagnosis, with a negative spinal tap.

Diagnostic testing for MS should always include both brain and spine MRIs. A CT scan is not the test of choice for neurological problems, it isn't reliable for revealing demyelinating lesions. You should have two brain MRIs, one with contrast and one without.

An MS diagnosis is made after several different tests are done, which include MRIs; a neurological exam that evaluates coordination, balance, strength, and reflexes; a spinal tap that looks for inflammation in the spinal fluid; and evoked potentials that measure the speed of electrical impulses from the eye to the brain (and from the ear to the brain).

Logging a symptom history and tracking the patient over time with repeated testing is usually how it goes and a diagnosis can take a long while for some of us. Multiple Sclerosis is hard to diagnose, there are many conditions that can cause similar symptoms. An MS diagnosis involves a process of elimination; it's MS if it can't be anything else.

Hope this helps.
