MG is myasthenia gravis, its an autoimmune disease that can weaken different muscles, including swallowing. I've had trouble swallowing with MG and it is scarey. http://www.myasthenia.org and http://www.myastheniagravis.org are 2 foundations out there with websites that describe the condition. its also described on mayo's website at https://www.mayoclinic.org/diseases-conditions/myasthenia-gravis/symptoms-causes/syc-20352036

it's possible to have trouble swallowing without droppy eyelids.
