Shalynn, I'm sorry they are happening. What it sounds like to me is that, if you do indeed have MG, it is getting worse. A few months before my MG crisis, I would have a sudden shortness of breath episode while out. If I rested, it would get better and then I would back off on activity. But three months after they started, due to doing too much and the heat outside, I went into a crisis.

A crisis can happen suddenly like that. The best thing you can do is to call your neuro and/or go to the ER to be checked out.

One thing you should know about B12 is that we need B12 for acetylcholine (B12 contributes to choline, which contributes to acetylcholine). I think you have more than one thing going on here.

You really need to get on the phone and call your neuro's office right away. If you cannot take a breath in or well, it's really an emergency. You cannot tell how quickly MG will get worse or how bad it's going to get. Having an "official" diagnosis is not necessary if you are feeling bad. You need to go in and let the experts evaluate you.

I hope you don't get worse. At some point, you may want a pulmonologist to evaluate your breathing thoroughly.

Take care,
Annie
