Hi! About 7 weeks ago I injured my left knee. Small tear to meniscus, small tear to ACL, sprained ACL, femoral condyle fracture. I was hit by a large wave in the ocean. Anyway, about 3 weeks ago I was diagnosed with fibromyalgia. I have had pain all over my body except for yesterday and today. 
What reeeaaaallllyyyy has hurt yesterday and today is my left knee and the two bones that go from my knee to my ankle ( tibia and fibula). Can fibromyalgia create greater pain to my injured left knee and bones? I can’t tell if I re injured my knee or the fibro is intensifying the pain. What is your experience? For some reason, yesterday and today I have had little “ body pain” . Very strange. I’m very new to fibromyalgia. For three weeks I’ve had severe body pain all over with a lot of fatigue and a pinch of fibro fog. Again, except for my knee, yesterday and today were good. Is this normal? Thanks for sharing your experiences!
For me, my Fibro pain hits where I have been injured before. I broke my right ankle last March & the Ankle Dr told me it could take up to a yr & a half to completely heal. Soooo hopefully this Sept it will be healed. Unfortunately, my answer to you is yes. I have good days & bad days & very bad days. What gets “attacked” most is my lower back, right wrist & right ankle. Call your PCP to make sure he/she knows what is going on. Peace, Light & Love
