Oh God i have those lumps in my upper arms thats how i went to get checked g/f has FM she knew some of my symptoms told me she bet me a case of beer lol that i had it ...i guess its time to pay her lol...i figured u have to have a sense of humor ..
I have been in contact with others who describe a lumpiness, like a knotting of muscles, who have fibro. Just to be on the safe side, I would have them checked out by your physician. They could be some type of fatty tissue and shouldn't be a problem as long as they aren't giving you a lot of pain.
Hope you feel better soon. I know those trigger points in the hips are awful to experience. Please take care of yourself.
