Hi all,

I would like to share my symptoms with all of you in the hopes that someone can tell me if I should pursue MG investigations.

Here is my story: left eyelid droop (intermittent) since the age of 20 or so (I am now 40); feeling of eyes wanting to go out of focus (especially bad after physical exertion such as running/lifting heavy objects), easy fatiguability of arm/shoulder/neck muscles (eg difficulty holding a phone up to my ear or rifling through clothes overhead when shopping), unrelenting fatigue and general feeling of weakness, brain fog (especially bad after physical exertion), bad reaction to an aminoglycoside antibiotic recently, weak voice projection at times, occasional breathing difficulties when laying down (usually resolves after a few minutes), muscle soreness that seems disproportionate to the activity that precipitated it, and prolonged fatigue and recovery period following exercise.

I have had the achr (?) blood test which was negative, but positive IgG (?). Recently, I tried an aminoglycoside antibiotic that left me laid up on the couch feeling weak and nauseaus (1st time trying this type of antibiotic).

With a negative achr, should I assume that MG is not a possibility...or has anyone out there been dx'd with MG after a negative result. Do my symptoms resemble anyone else's? I was told that muscle pain and fatigue are not symptoms of MG, so am not sure what to think.

I am looking for some direction to pursue as many of my other tests (eg lupus, etc) are negative, but I have felt awful now for the past 5-10 years.

Thanks in advance...
