Toes twitching (moving!) and scared

[ecann32]

Hi there, I must say that I am stone-cold terrified after a little over a month of toe twitching.  I am a 52 year old female. These are involuntary movements affecting both feet, multiple toes, but especially my big and fourth toes.  I have no muscle weakness.  Has anyone else had this, or does anyone have any expertise to weigh in?  Some more background: I can see twitching on and off in the arches of my feet, and this morning I noticed some twitching in my left inner heel.  Until now, the twitching had been worse on the right foot.  This started about 4.5 weeks ago with a bad bout of cramping in both feet.  Exercise /physical energy has not been affected.   I actually had a normal neuro visit about 2 weeks in (in so far as office tests, EEG & EMG).  Of course I was encouraged by the unremarkable EMG, but have recently heard that this may have been too early to diagnose A**?  Which I am extremely worried about.  Then to go further, I had a 3-day migraine-like headache this past weekend.  I have always had period migraines, but since I went into immediate menopause (torsed ovary), my migraines have changed to this dull, 1-sided ache that causes nausea and is resistant to my normal Advil. Lastes 2 days.  Also, that 1 side gets very stuffed up.  The bottom line is that now, in addition to A** I am convinced that the alternative is a brain tumor, after reading that brain tumor headaches present exactly this way!  I have gotten these same headaches about one every 3 mos. for the last 1.5 years or so. Of course, as a lifetime migrainer, I didn't think they were so much cause for concern. I even went to the ER one, although the headache subsided when I was admitted and they dx'd me with benign position vertigo.  One thing I noticed was that in the last 2 days, (basically during the migraine), the foot twitches died down/went away!  However, now that the migraine is gone, my toes/feet have been twitching all morning.  
1. Is there anyone else who has entered into the hell of this toe-twitching?
2. Is there a medical professional who might have an opinion about all of this?  I am awaiting MRI's of brain/spine.  Thank you!

Let me add that my bloodtests/electrolytes were normal, except for a newly elevated thyroid (TSH?) reading of 5.08.  Thx for any responses!
