Sandy, I'm sorry you had that reaction. A causal relationship is really hard to determine. Do you know the brand of the paint and what type it was?

You were out in the sun, correct? That alone can tank MG. There is also a sun-lupus connection and lupus patients can get angioedema. Have you ever been checked for lupus?

Beta blockers are relatively contraindicated in MG.

Did they determine the cause of tachycardia? Was it MG? Or did they just throw a drug at it?

When MG is worse, the heart beats faster to get us more oxygen. When that fails, the heart rate can go higher and oxygen saturation drops. Did anyone check your arterial blood gases?! O2?

You might also be dehydrated.

You may need to consult with an endocrinologist as well.

I hope you will seek out help in an ER if you continue to be so bad.
