You two had posted a couple of months ago regarding respiratory muscle weakness and I had responded. Both of you gave me your email but neither has responded. I was wondering if you had received it? I have had some testing done, but have no definitive answer yet, although it is looking like mitochondrial myopathy. My jaw muscle has been weak this week while chewing, do you guys have that as well? My resp. status is stable, with my MIPs and MEPs being 40% of predicted. I would appreciate any info.
