Effect of sympathetic nerve block on acute inflammatory pain and hyperalgesia.
Sympathetic nerve blocks relieve pain in certain chronic pain states, but the role of the sympathetic pathways in acute pain is unclear. Thus the authors wanted to determine whether a sympathetic block could reduce acute pain and hyperalgesia after a heat injury in healthy volunteers. ⋯ Sympathetic nerve block did not change acute inflammatory pain or hyperalgesia after a heat injury in human skin.
