@migizii My doctor said a way to tell if I'm in a Fibro flare is if my pain suddenly jumps on the pain scale by 3 points or more and if another symptom worsens suddenly. So let's say my pain level is usually a 4 but now it's 7 or higher and my normally clear head is now foggy, and I'm extremely tired....that's my sign of flare.
You mentioned you take meds for migraines. Do you take any meds for Fibro?
