My neurologist always told me that a respiratory crises comes on slowly. I think getting this checked out would be a good idea. Could be a viral thing too.

I am no MG expert (I haven't even been diagnosed yet, my neuro suggested that I may be in the early stages and is monitoring my symptoms), but you should definitely discuss those symptoms with your doctor, ASAP. Whether it is an impending MG crisis, a virus or something like undiagnosed asthma, anything involving your lungs is important and it doesn't hurt to ask your medical proffesional.

Breathing problems are normal with MG, but should not be treated as if they are normal. My own strategy was if I had breathing problems, first I sat in a comfortable chair and tried to relax and do nothing but watch TV to keep my mind from the breathing and getting panicky. I also took a mestinon tablet right away (my prescription was "as needed"). Only once did that not work -- I had walked several blocks to my neuro appointment and couldn't breathe decently and he sent me immediately to the hospital neuro wing where I stayed a few days. The solution there was more mestinon more often while prednisone was still not working.
Before I had the MG diagnosis and was already having problems, I was diagnosed with sleep apnea and got a CPAP (breathing assistance machine). When I had MG breathing problems, I found using the CPAP (an auto one that made it easy to breath out and pushed air in) made things OK. Eventually MG symptoms disappeared as prednisone worked.
With MG, we are almost always better to go to the ER than not, especially at first when things are uncertain. Also when we take immune system lowering meds (most of the drugs used long term for MG) there are so many chances for other problems that can rapidly take over -- sooner is better than later. I had all sorts of problems that normally my immune system would have solved but I had to take antibiotics to get rid of under prednisone.
Good Luck

Yes go !!!!

when it comes to your breathing at the very least call your neuro or go to the E.R. because it can get worse fast!!
Hope this helps

hi, i joined this forum today so i am hoping your breathing is better. My neuro has clearly given instructions on breathing saying that if you have a breathing problem, be it because of a fever a cold or a cough, show it to the doc. If the doc is a General practitioner, he should be in sync with the neuro.
Any breathing issues, it has to be shown to the neuro too because apparently when it fails it fails real bad with limited time on hand. so its better to be careful.
