Dale, I hope you went ahead and went to the ER. I hope you received the care you needed to feel better.

You need to contact your doctor’s office for questions like this.

One note- make sure you are staying hydrated (unless you.have a condition where you limit water intake for a reason).

Dale, this has been happening to me as well. Before I was diagnosed, doctors would send me to specialist after specialist and expensive test after test to check my lungs and my heart. Always the result was "your lungs and heart are just fine". Now that I have been diagnosed with MG, I still get the short of breath, impaired breathing, dizzy, headache. I actually asked my neurologist just the other day as to what his advice was on when I should seek immediate care if these symptoms happen again, and he had the nerve to say to me "Mary, I do not think that the Short of breath, impaired breathing, dizzy, headache are symptoms of MG!!" I get so so very frustrated when these types of comments come out of a supposedly "well trained" physicians mouth. It is times like that, that I feel quite stupid to be even sitting in the doctors office and want to just stop talking and can't wait to get out of there.

My Doctor told me if you experience any breathing or swallowing issues. You should go to the emergency hospital immediately. Wish you the best
