You may have Fibromyalgia or Myofascial Pain. Myofascial pain generally is in both sexes.
Myofascial pain is localized pain , whereas fibromyalgia has generalized pain.
All Ages have myofascial pain, whereas fibromyalgia is in the 35-65 age group. Changes in spinal fluid endorphine concentrations are potentially etiological in MPS, whereas, peripheral substance P production and alteration is most important in fibromyalgia. Myofascial pain can be either acute or chronic, but nearly all fibromyalgia patients are chronic, involving months to years of history. Myofascial patients commonly radiate pain from trigger points which are considered to be active, whereas fibromyalgia rarely has radiation. Fibromyalgia patients rarely have twitch responses.
