I've read it does, go into remission but only the pain subsides. I'm not sure what the longest period of time the remission lasts either. Here is just one of many articles that say it does go into remission.
Are there Periods of Remission for Fibromyalgia? http://www.fibromyalgiatreating.com/are-there-p...

the only time I can have a remission is when I rest inbetween chores..or whatever I am doing..but I find this really hard to do..because in life seems there is always something that needs to be done...and I always feel the pain rising..if I do not stop..and return later..also there are so many helpful tips..like 1 is I cook dinner in the morning or afternoon...because I know by night..it was cause way too much pain..from other chores I had done..I also pay attention to the more tired I am the more wired I get..and try not to go with it..as soon as I get wired I stop....and allwo the body to rest...the body pours adrenaline into our system to help aid us to get things done...but usually adrenaline is for emergency aid...but since we dont stop...we get the adrenaline rush...thats a hard one..but going with the wired-ness..makes flares come back to back..our body does not make peptides which should aid us in many things.sleep rest happiness..aid pain etc...so our central nervous system is out of whack..so we have to be the judge of how much the pain is rising as we do things..and hopefully stop and rest inbetween

I havent heard that it does, but good question. My personal experience is having ups and downs. Periods of feeling really good but then weather, over doing an activity or doing things to many days in a row, stress and oh my the list goes on with triggers.
Take care!

I've never heard that it does. Let us know, if you find out.

Thanks, ladies! There's hope...☺️
