I know that this sounds weird, but when I get tired, especially when I am lecturing for several hours, my right ear stops up. My nose also stops up. My right eye will go all blurry and my voice will start to go out. I know that the eye and the voice is due to the MG and it happens less severely with the mestinon and it gets better pretty quickly with rest. The stopped up ear and nose also gets better with rest. I have assumed that the ear thing was allergy. I have even considered getting surgery for the nose. This is not just a little bit of a problem. The whole thing makes me sound like Hank Williams Jr. It makes me miserable. So is the whole thing possibly all MG related? I can go up a tiny bit on my mestinon dosage if that would help.
