It sounds to me like you finally found a doctor who is actually "objective" and can see you have MG. That's FANTASTIC! Thank you, Oxford doctor.
I hope what this means for you in very real terms is a better MG treatment plan, better treatment by these other doctors and a higher quality of life. I have to tell you, I was really worried about you. Those O2 saturations of yours are dangerous.
I hope you will have a very good night's sleep tonight, knowing that someone FINALLY took you seriously. They should've taken the disease seriously a long time ago.
Now you probably have to make decisions about what treatments to have. Sounds like they'll try plasmapheresis first. Read up on it - in a couple days.
Thanks for telling us how it went. Like Nicky, I'm very relieved.
