Opposition to anesthesia has since dissipated; however, the prospect of eradicating pain raises similar concerns about interfering with life's natural functions. [ 2 ] People who are naturally incapable of feeling pain or unpleasant sensations due to rare conditions like pain asymbolia or congenital insensitivity to pain have been studied to ...
Local anesthesia is any technique to induce the absence of sensation in a specific part of the body, [1] generally for the aim of inducing local analgesia, i.e. local insensitivity to pain, although other local senses may be affected as well. It allows patients to undergo surgical and dental procedures with
The hallmark of the disease is the marked loss of pain and temperature sensation in the distal parts of the lower limbs. The autonomic disturbances, if present, manifest as sweating abnormalities. [1] [2] The beginning of the disease varies between adolescence and adulthood.
