Dear starburst,
Fire the neurologist who diagnoses you with panic disorder, run like the wind. Forget all about that and stick with your MS specialist, who sounds a bit less idiotic.
Have you had a cervical spine MRI? That should be a standard part of your MS tests. The specialist has it right when he/she says there are probably lesions that aren't showing up on the scan. MRIs don't show the whole picture for a number of reasons.
Lots of us have heard that we don't have typical MS brain lesions and got the diagnosis anyway, there isn't much about each individual case of MS that is typical in the real world. An MS dx is made based upon your symptoms and history, physical exams that test your balance, strength, reflexes, coordination and sensation, MRIs, EPTs, lumbar puncture results, and after other conditions have been ruled out and it can't be anything else but MS.
Delayed menstruation can be a result of stress, hormone imbalance, perimenopause, or a number of other things. You might want to see your OB/GYN about that. We MSers do develop medical problems that are unrelated and we are often tempted to blame MS for everything.
Not sure why foods would cause dizziness and fatigue in the morning. Multiple Sclerosis can definitely make us dizzy and fatigued in the a.m., however. Add heat, or allergies, or a falling barometer, or another medical condition, MS doesn't play well with others. You'll definitely want to mention the food=dizziness fatigue equation to your doctor, hopefully they'll pay attention and give you some thoughtful explanations and advice.
Hang in there.
Kim
