Hihi Rach,
so sorry to hear about what you are going through. I was just as frustrated as you are when i simply couldn't get a diagnosis, even though i practically couldn't walk. my limbs would tremble too, and some of your symptoms are what i am feeling too, love the bit on having an elephant on your chest!
a note about emg though, i just redid my emg at another hospital and they've found some abnormalities in my emg, though the first hospital i did it at couldn't find anything wrong. Its just a mth difference between the two tests so i myself am flabbergasted.
Initially i was diagnosed as having conversion disorder and referred to a psychiatrist as well as a psychologists, nad amazingly i managed to convince both i didnt have conversion disorder, and got them to write a letter that my symptoms weren't due to mood or stress symptoms. that letter helped me in getting that diagnosis revoked, as in singapore, our medical records are shared between hospitals too. =) I too thought i was going crazy, but it was more due to the symptoms rather than any existing mental or mood stress that i had, and the psychologist and psychiatrist both agreed.
Mg's quite rare in Singapore where I was, so now am overseas trying to get a proper diagnosis. I agree with Annie, even if its not MG, it could be another muscle disease or other health issues which need medical help! Do not give up on yourself, the symptoms u are experiencing can't be due to you wanting to feel them. Its crazy for them to even suggest that.
