For the pat 5 years or so I have experienced spasms in my throat which make it impossible to inhale. It's terrifying, but I have learned that I need to force myself to relax when it happens so that my throat will open. My dr. says that if I pass out, my throat will relax and I'll be able to breathe again, but that's not much comfort. I was diagnosed with fibro. about 15 years ago....chronic muscle spasms in my back and legs are my worst symtoms. I don't know if this throat problem is a part of the fibro or not. Anyone else have this problem?
