Dizzy, Blurred Vision, Pins & Needles, Burning Sensation but clean MRI's, Evoked Potentials, etc

For 7 months I have been suffering from dizziness, blurriness, nauseous, pins and needles in my hands and feet, pain in my right arm, burning sensations throughout my body, fatigue and initially experienced a weakness on my right side.  My symptoms seem to me to be classic Multiple Sclerosis.  However all of my tests have been negative.  I have had MRI's of Brain & Spine, Visual Evoked Potential, SER, BAER, and all shorts of test to rule out my middle ear.  My DR's haven't been willing to treat me for MS because so far they do not see any lesions.  However They also do not offer any other possible explanation for my problems.  My condition seems to have gotten worse over the last 7 months and I feel like the DRs are waiting for a bigger attack before they treat me.  Am I alone out there?  Does anyone have any suggestions for me?
