Patient discussion about fog

Q. In what way the brain fog symptom associated with fibromyalgia? In what way the brain fog symptom associated with fibromyalgia? What are the other symptoms of fibromyalgia?

A. memory loss is also associated with Fibromyalgia...lack of concentration and you just feel like you are in a fog...can't remember....can't think. Our standing joke at my house is "I am in the "fog" today. The one thing my doctor ALWAYS reminds me of fibro affects people differently, remember you may not have all the sympoms or you may have ones others don't but fibromyalgia is widespread pain that has lasted 3 months or more, it is pain of the fibrous tissue - ligiments, tendons and muscles. You feel stiff and achy all over. There are trigger points such as neck, shoulders, spine and hips. Chronic fatigue taht is possibly related to the disturbed sleep patterns. Most suffers I have talked to have restless leg syndrome and headaches. Irritable bowl is associated but on that one I am lucky I haven't had the problem but have had swolling problems and vision problems...I hope this helps. Good Luck!
