Is the 'vibrating muscles' sensation unique to LEMS? Since all these symptoms started happening, I'd assumed all the bodily changes were MG so I don't know how to distinguish between MG symptoms and LEMS symptoms. Do you guys get undue muscle pain when the muscle is pressed on? That just started for me. Is that LEMS or could it just be a symptom of muscle wasting?

When it was at its worst, I felt a tightening (the sensation of a clay mask drying on the skin) roaming across my face distorting my eye, forehead, locking my jaw, causing a strangling sensation across my neck.... The tightening was actually flickering on & off, ebbing & rising and would allow me to talk then making it hard to move again. Is that a LEMS symptom? Or MG? or both?

For two weeks, my throat has been spasming (I assume it's a spasm) that alters my voice to soprano range when I talk. My voice returns to normal range if I have food in my cheek, tilt my head forward or backward, if I drink, eat, cough, burp or sneeze. Then I'm reverted to soprano again within 1-5 seconds. Is that a LEMS symptom? Or MG? or both?
