Hi, rMuD. Welcome.

HLA B27 is associated with Ankylosing Spondylitis.

Do you have a good primary doctor or endocrinologist? Having your thyroid tested, especially if you have MG, is a very smart thing to do AND on a regular basis. Many people with MG have some sort of thyroid problem. Stupid doctor.

Have you had your vitamin B12 checked? If not, I highly recommend you do, plus your vitamin D level. Those are very common deficiencies.

Obviously, you do have things wrong with your health. And MG can be life-threatening. Kind of hard to go on with one's life when one is so weak and unable!

I hope you will start receiving the care that you deserve!

Annie
