Does this sound like MG?

I have had alot of wierd symptoms for about 3 years.  I am a 31 year old female.  I have muscle twitching and migraine headaches at least once a week.  Often my muscles feel weak.  I can still use them, but they feel tired.  I think this is called perceived weakness.  I have one eye that is smaller than the other.  (ptsosis?)  I also have one eye that shoots outward, causing double vision.  The double vision clears up as soon as I blink and my eyes reallign.  I have seen 4 eye Drs about this, and have been diagnosed with convergence insuffiency.  The double vision happens anytime I try to focus on objects near or far.  Recent blood work has shown anemia, which I read can be associated with thymoma.

I am concerned because of the research I have done, alot of my symptoms sound like MG.  I am really scared and would like some advice.  I am a hypochondriac and have seen many Drs, but so far they have found nothing.  I have not had an EMG or anything like that done.  

Thanks for any advice you can give.

Hi there. Ocular MG is a disease of the neuromuscular junction resulting in muscle weakness and fatigability. This is an autoimmune disease where anomalous antibodies are produced against the acetylcholine receptors in voluntary muscles. The most common presentation is double vision and eyelid drooping or ptosis wherea the pupil is spared. Diplopia is seen when MG affects a single extraocular muscle in one eye, limiting eye movement and leading to double vision. Ptosis occurs when levator palpebrae is affected on one or both sides. the features of ptosis associated with MG are asymmetric, worsens with fatigue, sustained up gaze and at the end of the day and gaze evoked nystagmus, and Cogan’s lid twitch where upper lid twitch is present when you look straight ahead after looking down for 10-15 secs. Consult with your neurologist in detail with these speculations. Take care.
