What is the difference between breathing problems resulting from stress and those resulting from MG?


I´m thinking that if you have MG breathing problems, wouldn´t you feel the discomfort out to the side of the ribs where the intercostal muscles are and slightly lower down?
Mine feels like it´s way too high up near the sternum area and where doctors previously have put it down to some underlying stress factor.

I just went back to work after a really long holiday and now have to project my voice 4 hours a day during an 8 hour work day. So I know this is when it has all started.

Things like......

• Quite often I catch that my breathing is so shallow that the lungs are barely moving

• This week I had to avoid lunch with work colleagues since eating and talking at the same time was impossible

• Last year I sometimes could not finish a sentence and now there are times where I can not start one.

• Fluctuating weak cough here and there and problems with breathing ´in´ but not out.

• Avoiding heavier necklaces and tight clothes on upper body which feel tight only when the´breathing in´ problems are present.

• 2 days ago I spent 4 hours of working way harder than normal to get the air into my lungs. I took Mestinon for some double vision I was having and by default the breathing improved dramatically - but I would really need to try a few more times to be certain it was the Mestinon that did that.


Do any of you have anything similar with your breathing? Or does it seem to be more fitting to a stress profile?
