Case 416. (Weygandt, January, 1915.)

A German volunteer, a sportsman, was under heavy shell fire after the middle of October, 1914, and was wounded in the upper arm in November, with an injury to the median nerve that occasioned severe pain. These strictly localized pains increased upon any sort of physical or mental strain. If he walked down steps he kept thinking he might have an accident, and then the pains set in with greater force. He became apathetic so that he did not eat, drink or urinate. If his head were touched he felt pain as if from an electric shock. He also felt the pain when he saw anybody approaching a door to close it, through apprehension of the noise. Meantime, the wound was well healed. The pulse was accelerated. The visual fields were only slightly contracted. The patient wanted to get well and go back to the service.

Weygandt regards this hyperalgesia after peripheral nerve injuries as neurasthenic.
