With fibromyalgia it is usually a secondary condition to something else,usually if you have fibro you end up with a duel diagnosis. I explain it best in my blog at myword.live I wrote an article about fibromyalgia after much research

Yes I suffer WITH it..SUMTIMES my hands change colour & fingers go white & also my FEET can change COLOUR .was aa prescribed blood pressure tablets 4it.
but it didnt seem to help .x

Dear Wayne Frost:I too suffer from raynauds:it also another lovely issue that goes right along with the fibro:( it's worse in the colder months I once thought I had perminant frostbite !my hands are usually cold as are my feet!they turn kinda white then blue and then purple and back to red.its very painful. They also tingle a lot .i also have a job where I am in and out of a sub -zero freezer all day!so yes brother I feel your pain!doctors1&2suggested I get a different job!easy for them to say! No easy answers for this except keep them warm,moisturize.

I do. My hands and feet lose all circulation and turn so white it seems like you can look through them. It is such an awful thing. It hurts very bad when circulation comes back. My doctor knows i have it but said there was nothing that could be done about it. The only thing she offered was to keep my hands and feet as warm as possible.😟

I suffer from Raynaud’s disease and am on strong calcium blockers which help a lot xx
