Fibro or Benzodiazepine Withdrawal Syndrome?

I was prescribed Clonazepam for 12 years for insomnia and anxiety. I was married to a physically and mentally abusive man, so I also have PTSD. Didn’t know anything about benzos. 6 years ago started having pain in neck, traps, jaw, head, arms, chest, thoracic. I never raised my dose, so I may have reached “tolerance”. Over the years pain gradually worsened and included a few other minor symptoms. 28 mo ago went to treatment for PTSD and chronic pain. They tapered in 10 days. Disaster!!! Pain went from 5 to 8 and has stayed. One day out of 8-10 weeks, might have tolerable symptoms. Muscles burning, stabbing, and pulling in those areas, numb fingers and face, tremor, confusion, dissociation, dizzy feeling of movement, numb hands and face, tinnitus, malaise, bouts of diarrhea, achellis tendinitis, sensitivity and or allergies to medications (can’t take ANY meds usually prescribed for Fibro!) and foods, and plenty more. I’ve seen dr after dr for diagnosis and have been to 4 treatment centers for chronic pain and PTSD. All say it’s PTSD. Last week I was diagnosed with Fibro. But what about benzos and the subsequent Benzodiazepine Withdrawal Syndrome? Every symptom is identical! See: benzoinfo.com . It’s hard to believe, but 4 of 4 treatment centers did not acknowledge this syndrome and only 2 out of many many healthcare providers have ever even heard of it. The hypothesis is the two may be linked as a causation. See: Pubmed, How Chronic Administration of Benzodiazepines Leads to Unexplained Chronic Illness. Just curious, how many of you were prescribed benzos, longer than a few weeks prior to Fibro diagnosis? What do you think about this possible link?
Thank You.
