Myasthenia gravis (MG) is a neuromuscular disease leading to fluctuating muscle weakness and fatiguability. The hallmark of myasthenia gravis is muscle weakness that increases during periods of activity and improves after periods of rest. Although myasthenia gravis may affect any voluntary muscle, muscles that control eye and eyelid movement, facial expression, and...
Many of us have bad stories of how our diagnosis was missed, sometimes for years as doctors don't think about MG as it is very rare.
My early symptoms were eyes -- double vision and one eye kept going shut. My eye doctor did the "ice pack test." He put an ice pack on my eyes for about two minutes and when he took it off for a few minutes both eye lids stayed open fine.
Then he ordered a blood test for MG (ACHR) which came back positive. That meant that my immune system was making antibodies that attacked the connection between my nerves and my muscles making the communication poor. Treatment for me was prednisone to slow down my immune system making the problem antibodies and in a few months I was feeling almost normal again. MG treatment works for most of us, but as MG is not curable, just treatable, we have to continue treatment most of our lives (there are cases of remission).
MG is different than other conditions in that we still have muscles that work,but when we use them they tire very quickly. One of the tests for MG is actually seeing if the muscles work and then tire more rapidly than a normal person's. My doctor would say - grab my hands and try to pull against mine -- and for maybe 10-20 seconds I could equal his strength, but then mine gave out while he was still pulling normally. The test done in the clinic is a single fiber emg, and it essentially tests how quickly a muscle tires.
Another way of helping to decide if MG is the problem, is to take a pyridostigimine (brand name Mestinon) pill. For most of us with MG, 30 minutes or so after taking the pill we feel stronger for then next few hours and then it wears off. Mestinon improves the nerve to muscle communication temporarily.. As it almost only works for folks with MG, a clear improvement with a pill is a strong pointer to MG.
Hope you don't have MG. However, if you do, most of us come to the diagnosis in rough shape, have several more months with problems, get our immune system suppressed and then get back to living OK. Some have more problems, but most figure out treatment and get a decent life back.
Good Luck

Sorry to hear you are having so many problems. Several discussions here in the past have covered Rituxan/Rituximab for refractory MG. Part of the difficulty is in getting it paid for by insurance, but Rituxan does seem to be fast acting and successful for many folks as well as much less inconvenient to use. Cellcept and Azathioprine (Imuran) are standards for treatment and do work well for many folks, but take months to a year or more to become effective.
You can find out what has previously been discussed here with a google site search. When I search on Ritux myasthenia we find this list of discussions

A site search has the syntax ritux myasthenia site:https://www.dailystrength.org/ where you type in the search words followed by the word site:________________ with the web site. It is much better than the search you can do in dailysearch itself.
By the way, if you create your own post on this subject you will get more response rather than commenting on a post on a different topic
My own reading of several years of posts on Rituxan seems to show it is used in refractory (hard to treat) folks and has been pretty successful. It would seem to be worth trying. The FDA won't approve it until many research studies are done in treating MG. That may not happen soon. One study you can read shows positive results.
With musk MG, treatments that work for ACHR MG may not work the same or may not work at all.
Here is a research result https://myastheniagravisnews.com/2018/05/29/myasthenia-gravis-rituxan-improves-muscle-strength-long-term-data/
Remember, if you have musk, you need to try to read what treatments work of that variation of MG
Good Luck
