It is very important that you check wether you have taken any quinolone antibiotic in the past 1,5 years or so.
Very common antibiotics of this class are cipro and levaquin but also tequin.
If you have taken those antibiotics you might be suffering an adverse reaction. Your symptoms fit very well with the signs described for that kind of side effects.
I think you can start by seeing your primary care doctor. Your symptoms do not point to one particular diagnosis. Without examining you I could not refine an opinion further. Your doctor should be able to review your findings, and then make the appropriate referrals and tests. Good luck.
Should add I am male, 40 years no family history and eyebrow twitching is todays little pleasure - could this be caused by eye strain ?
