The last two weeks have been bad., I have the myasthenia , but luckily not terrbly, mostly my eyes and face and fatigue., but now they say I have rheumatoid arthritis, my hands wrists and fingers are so painful , swollen and hot, it is almost to the point of incapaciting me.,especially at work., they are doing some blood work and testing., my physician says sometimes with one autoimmune disease another will follow. Anyone else have this happen. I am afraid I am not going to be able to work.
