We concur that a brief description of the literature regarding EIH in FM is warranted and have added information to the discussion as follows: “Previous research regarding the effects of acute bouts of exercise on pain sensitivity in FM patients is largely equivocal. Some studies have demonstrated a hypoalgesic effect [5,24] while other studies show either no changes in pain perception or an exacerbation of pain [25–27].”
We feel that the manuscript has been significantly improved as a result of the suggested revisions.
