Hi Catherine,
Sad to say I've never heard of it. I googled it and got one website only, in garbled Russian. So I'm non the wiser.
It's not Myofascial Pain Syndrome, is it? The info I found on this site:

sounded like it could be.
Useless, aren't I!! Hope there's someone here who can help more...
all the best,
