My reasoning for this question:

  • In both situations, you see a cyclical increase in pain before receiving the injection. This could be seen if the effect was wearing off; however, if you notice, there is a decrease in pain before the injection is even given. I believe this implies that something inherent about the injection is providing pain relief.
  • Furthermore, both curves follow the same path with an eventual decrease in pain, regardless of intervention.
  • Maybe an additional point - I am not questioning their pain, but fibromyalgia typically shows no abnormal lab results in addition to typically coexisting with some form of mental pathology. I don't think placebo being demonstrated is far off.
