I am going to the MS clinic and so far all tests have been normal except the reflex test in the office. MRI's, Blood and LP have been normal. My doctor agrees that something is wrong but at this point nothing to point to. After my recent LP she asked me to go for a EVP test. I am wondering if anyone has been diagnosed by the EVP or if other tests also have to verify. She wants to see me back in 6 mos. or sooner if anything changes. I of course have all the classic or not so classic as the case may be symptoms. So is this something to consider? or not?
