lesions in pons area of brain causing dizziness and stiffnes

Hi, I am 35 years old and have been dealing with episodes for the past 7 years of headaches behind the right eye, balled up muscle stiffness, difficutly walking fatigue, neurgenic bladder, dizziness. The summer of 2007 the dizziness has been so bad and I had a hard time staying awake the entire summer. I went to a neurologist which i told her my symptoms and she did a Brain MRI and discovered I have two leasions in the pons area of my brain and thats why i'm having such a hard time staying awake. The doctor put me on adderall to keep me awake. It seems to be working fine but, I'm still having issues of dizziness which can last every day, lasting for an hour to 8 hours a day and has been going on for almost a year now and doesn't seem to be going away. I do know that If I don't get enough rest, or I'm out in the cold it will bring on my other symptoms of balled up muscle stiffness.

The doctor is thinking of putting in the catagory of Mixed connective tissue disease for now. All I want is for the dizziness to stop. Has anyone had this problems? Especially the longs periods of dizziness? I have had my inner ear checked and Have been to an ENT Doc and they said everything was ok.
