Definitely talk to a neurologist about Myasthenia Gravis (MG). That’s where all my issues started-double vision and extreme extremity weakness when I was 17: after the birth of my first child (28), I was diagnosed with Sjogrens Syndrome and had major flare ups after the birth of my next two children. Then at 47 while going thru menopause I was diagnosed with Lupus and RA: I went into acute kidney failure (stage 3, almost 4) at 49. It’s been a rough road but find a good doctor to help you manage it all. The Mayo is fabulous if you can go there! I’ve noticed that a lot of my issues revolved around times in my life where I had hormonal changes. I hope you find answers! God bless!
