Hi I dont know if it's the same thing but i know that a lot of people with fibro me for one suffer from knots in the muscles and can be felt clearly when pressed they can be in any muscle in the body and really need to be massaged out to bring any kind of relief the knots or lumps can be come very painful if not stretched out and eased i know i feel as if i am in constant painful cramp My Hubby says he can feel these knots as he tries to massage them out !!
As for my feet i have suffered for at least 15yrs with what some call heel spurs (plantar faschities)
This can be a very painfull problem if not treated correctly even trying to stand can be painful I know this maybe nothing like what you have But i hope it helps and you feel better soon HUGS
