Hi, Several points. Fibromyalgia implies there is not an actual problem going on. If someone is stabbed repeatedly and goes ouch that is not fibromyalgia. Similarly, large stones falling on someone, pieces ripped off, severe inflammatory diseases requiring methotrexate, are all NOT fibromyalgia. Likewise, having a nerve inflammation treated with chemotherapy like methotrexate that is certainly dangerous and likely strongly carcinogenic is not ever EVER done. Not. Ever. So, I certainly cannot comment on your situation at all. Fibromyalgia is either a rather poor term which by being defined as having pain when ju jitsu pressure submit points are hit and not being entirely happy 100% of the time would include absolutely all of us. If it were a real condition of pain wiring dysfunction it would be like what I and 5% of those from my part of the world have where opiate receptors do not function. Fentanyl and opiates are at best utterly worthless for this. Rewiring the pain perception by non-opiate means is the standard practice. This might include any medicine that damps down nerves. Any anti-epileptic, any Lidocaine like drug, most arrhythmia medicines. Also, down regulation by constant small pain by doing moderate to high amounts of exercise daily will help. But, as mentioned, I cannot comment on your situation at all. Take care. Hope I have answered your question. Let me know if I can assist you further.
