Seriously, does Fibro not spare any part of the body? Unfortunately, I've learned recently how relentless it is. My voice has been hoarse for months. It began after an allergic reaction that caused hoarseness/throat closing. After a few scopes I learned my vocal cords aren't working properly (vocal cord paresis, thankfully not paralysis). Essentially my muscles are squeezing and pinching my vocal cords causing me to work harder to talk. After one voice therapy session (I have to go to therapy because I have to learn how to talk again without straining my voice) the therapist couldn't figure out why I wasn't doing so well at the exercises, so the second appointment she felt around/massaged my throat. She had to feel around at all my muscles - felt my upper back, neck and throat and then just stared at me in disbelief as to how tight it all was - literally my upper back is always as hard a rock. She asked me how long it had been like this, I told her 4 years since I got fibro. Basically she told me that my muscles were so tight in my back and neck and the tight muscles were now just tightening around my throat/vocal cords too! My response was disbelief and yet cynical because I've had enough of this already, I could only respond that of course that was what was happening because fibro is taking over every inch of my body... 
I have been using heat more often and trying to get massages weekly to try to loosen me up more in hopes that my muscles will take a break around my throat. I have been taught how to massage out the knots in my throat and it is soooo painful, but after I talk like a normal person - for at least a while. Since so much else has been going on with me I have been seeing my Internist and some Specialists regularly these past few months, one would think that something else would possibly be going on but all the tests have been normal (wonderful news!), so I'm just stuck with our good old friend that's been stirring up lots of trouble.
Has anyone else found that fibro is making its way into different places/parts that they never thought possible?
And I have to agree with Mrs_Mike, I think Fibromyalgia is a big jerk too!
