Go to Google and put in what are the signs of myasthenia gravis. See how many you have. I had diagnosed it myself before I went to the ER and judging by what I was told on WebMD I knew I had it.

I have lots of the symptoms however I have not tested positive on any of the tests. Difficulty swallowing, getting up from a chair, going up and down stairs, difficulty breathing at times, fatigue, feeling weak and heavy........

Sorry you are still having problems and that you can't find out what is wrong. Doctors see you for a short time and depend on what you tell them as well as running tests.
As the tests are negative, I think I would try to get as specific as I can about the symptoms. Keep a notebook and jot down what is the problem, when it happens, and where you think it is happening. For example:
Friday Oct 13 10 am had trouble carrying groceries to the car. Out of breath (or feeling weak in arms, legs ... etc.) Maybe you can start to see any patterns and you will also have a list of exactly what part of you is having a problem (eyes, arms, legs, breathing....).
You don't take the whole diary to the doctor, but study it yourself after a few weeks and see what you can pin down as the most common symptoms, when they occur and so on. Then you try to summarize it and when you see your doctor next time, you pick only one or two of the worst symptoms, tell him how often, when, and what level of weakness, pain, etc., you are having. Doctors just don't respond very well to overwhelming them with symptoms that are vague and intermittent. Maybe with details and limited information you can focus them on what is worst.
I worked most of my life with doctors (I was in research) and have heard them complain about how difficult it is to deal with general complaints of weakness, tiredness, etc, so getting them to focus on the main symptom or tow that seem worse might help get them to focus.
My mother had polymyalgia rheumatica (autoimmune system attacks most of your body) and her complaints of aching all over and fatigue were ignored (take tylenol) for many years until finally the doctor did a blood sedimentation test and found the sed rate was very high and began prednisone treatment (for the next 25 years).
Good Luck

Thanks Russ. I know how I feel, and sometimes wish they would walk in my shoes for just 1 day. I tell them I am fatigued and they tell me am probably depressed. I feel weak, can hardly do stairs, yet they tell me I am not clinically weak. Before this stared, I walked on the treadmill daily, for 30 minutes at 3.7 mph at a 3 % incline, now my 86 yr old mother walks faster than I do. Some days are better than others, some days terrible. No day is the same. I just hope the new neuro can figure this out. If it is not MG, I hope they just don't give up on me.

Sounds familiar! I too was told I was depressed and should start taking SSRI meds. I insisted I wasn't depressed, just something was physically wrong. Finally I got double vision and droopy eyes and my eye specialist did the ice pack test and told me he was 85% sure I had MG, ordered a blood test which confirmed it. Then, when I went back to my general doctor, told her "you see, there was something wrong--it wasn't mental." She apologized and offered no excuse, just that she was sorry she missed the diagnosis. MG is so rare most doctors don't see the early symptoms, just the glaringly obvious shut eye/double vision kind.
When I was hospitalized in an MG crisis (breathing), at Mayo Clinic, about a dozen young neurologists in various stages of their residency came in to visit me and ask if it would be OK if they went through the MG exams and tests with me--those of strength, looking up, ice pack etc. I was probably the first MG patient they had seen in their 3-year residency. Each one had a different approach. Some were sort of shy and tentative--holding back on doing the full exam; others very open and thorough, insisting they get all the information, details, and completely learn what they could from me. Having recently retired from Mayo (where I was hospitalized), and having worked with many residents myself, by the time they were all finished with me, I knew which ones would be my choice for my neurologist. Doctors are people and people are very different and it mattered to me to find one who not only listened, but explained and learned rather than just proclaimed.
Hope you find out soon what is wrong

I also had the buzzing , tremor sensations and was originally told it was anxiety. All my tests for MG were negative for many years till they finally did the Single Fiber EMG. As I have a sister with Multiple Sclerosis and a Father with Lupus, they were focused on those diseases. As far as the the vision I also get Migraines (with brain stem aura) that makes the existing eye muscles weaker than usual. Keep pushing for an answer, if your doctors "give up" on you as you stated, than see a new one.

Thanks. I am just hoping this new neuro does not give up. He seems to care, but we shall see. I am one to not complain, and I usually only go to my primary provider once a year for a check up. She sent me to a neuro because she believes me, however they just shrug me off. Seems nobody wants to dig deeper. I did have double vision for a very short duration when I was really tired and could not sleep. I looked at my alarm clock and saw double. Closed one eye and it was fine, but with both eyes open I saw double. It was gone the next morning after I finally got some sleep. Coincidences? I have had what they describe as an optical migraine a couple times. I Had One just the other day. No headache, just vision had floaties or auras, and blurry, but they don't last. It is hard to wait for an appointment when you just don't feel well, but I will not give up!!

Summer, hang in there. I am sure you will get an answer to all this soon. Ask around to others, especially the nurses in the neuro ward of a good hospital for information and as if they have any MG patients. It is hard to find someone with MG experience and then, try to see that neuro for some help. I am sure there are some qualified neurologist's in the area. Just gotta dig.

The EMG is not reliable for MG. I'm not sure a second one would help. Have you had your thyroid tested? If they only check the function and not the antibody count, they don't always detect the issue. My thyroid caused more exhaustion than the MG. good luck.

Yes. I only have 1/2 a thyroid, and honestly it has probably been checked 4 times this year. They did complete tests. I hope someone can help me soon. He is doing another EMG because he did not do the 1st one and wants to check for myopathy of any kind.

I went to Brigham and Women's in Summer 2016 and then Mass General in Summer 2017. Each appointment was a frustrating waste of time. They did a minimal exam and did not consider my symptoms. They each based their opinion of me my records. Since the first neuro I saw in Fall 2015 decided it was psycholgical - some (Not all) specialists I have seen have simply followed her lead without any consideration for what I say. The GI doctor and Physiatrist I am seeing have done a better neuro exam that any neuro I have seen. My eye lids do not seem to droop properly so I can not have MG per both Boston neuros. I have double vision, light sensitivity and my eyebrows droop... I am prescribed mestinon - that does help! and I am just starting prednisone. Funny when all this started the very first Specialist I saw - neuro eye exam in late summer 2015 said I had MG.. but no neuro ever seems to care. Little bitter today - just resigned from my job. Just can't do it any longer. Too long a time of dragging myself there when weak. Lots of muscle pain and tightness. My endo is looking for a good neruo in Ma or NH for me! Maybe I will try again. No records will be sent.

Wow Meng. Sorry to hear all the issues you are facing. When the symptoms really hit me, I was at work. I already suffered the fatigue, shortness of breath, and drooping right eyelid, but had chalked it all up to being fat, old and being already diagnosed with COPD and CHF. It was only when I could not say the number 6 on the phone one day that I knew something was really wrong. I put the symptoms into a google search and both WEB MD and another site suggested a stroke or maybe MG. Having been an EMT years ago, I did the stroke test and knew it was not that. So I drove myself to the hospital and on the way, I got weaker and weaker. By the time I got to the ER all I could think of was neurologist. I wrote on a piece of paper MG? After a few tests the on call neuro came in and said he had been to school a lot longer than me, but he thought so too. This was twelve months ago. Since then I have been in the hospital 5 more times, had 38 Plasmapheresis treatments and have had numerous medicine changes. Currently I am on 8-500mg mycophenolate tablets per day and 4-60mg mestinon tablets per day (along with pills for GI issues, heart issues, blood pressure, issues and diabetes issuse. The prednisone 20 mg per day is not going to be increased as it really messes with my diabetes. I have just seen my 6th neuro doctor and I am impressed with each one. My suggestion to you is to do some research on your own, and then research neuro's that are well versed in MG. Find a patient that has MG and thinks their doctor is good and do what you have to to get an appointment with that Dr. Best of luck and don't give up. Try this link. Just copy and paste, it's a start. http://www.massgeneral.org/conditions/condition.aspx?id=315

Meng , my Boston trip to Brigham was a wasted triptoo.I saw the supposed guru, a Dr. Amato, or should I say I saw his fellow, and the Dr. for 10 minutes. He mad me feel like I was lieing, and basically asked me what I wanted him to do for me. No tests nothing. Just told my my muscles were fine. Let me know how you make out. It is so frustrating to not have anyone listen, when you certainly know how you feel. I am on neuro number 3. If it's not MG then they need to figure out what it is. Best of luck, I know what you are going through.
