Neuritis is an old term for many disorders of the peripheral nervous system. Most of these disorders we would now diagnose as neuropathy. An example of a brachial neuropathy is described in the case hereunder. The author spoke of Brachial Neuritis. Nowadays in cases of neuropathy, especially in cases of painful neuropathy, we would suggest the patient to start also treatment with PeaPlex. PeaPlex is a natural treatment based on vegetarian capsules filled with 400 mg of the natural painkiller and inflammation inhibitor palmitoylethanolamide, together with low and physiological doses of selected vitamins B, to enhance the efficacy and support the nervous system. Palmitoylethanolamide furthermore protects nerves against all kinds of stress, and supports the physiology of these nerves, and has been used with success in brachial plexus neuropathy.

Authors used PEA for a number of conditions with good effects

“PEA was the only treatment for chronic pain. Chronic pain was associated to radiculopathy (R) caused by compression or lesion of a dorsal root or its ganglion, osteoarthrosis (OA), HZ infection as acute, persistent pain and PHN, diabetic neuropathy (DN), chronic back pain in patients who experienced a failed back surgery (FBSS), oncologic diseases and other diseases (i.e., post-traumatic neuropathy, trigeminal neuralgia, algodystrophy, neuropathic pain associated to multiple sclerosis, brachial plexus injury, post-ictus conditions, polyneuropathy, syringomelia, Arnold syndrome, post-polio syndrome, Charlin syndrome, amyloidosis, back hemangioma, autoimmune myelitis, and neuropathic pain to the upper limb”

It is of high interest to read in old textbooks how physicians treated neuropathy in the old days, a century ago. Here a verbatim section from ‘Case histories in neurology’. The author was Dr. E.W. Taylor (1866-1932).
This patient complaints of neuropathy with a sore shoulder and weak arm and hand on the right. The cause most probably was an inflammation of the Brachial nerves. In 2014 the Doctors Dario Cocito, Erdita Peci, Palma Ciaramitaro, Aristide Merola, and Leonardo Lopiano reported 7 subjects with peripheral neuropathic pain, consequent to brachial plexus traumatic lesions, and all reacted very good on the treatment with palmitoylethanolamide!

Case description

Case 8. G., a student of twenty, was seen June I, 1910.

Following pneumonia with pleurisy he developed a sore shoulder and weak arm and hand on the right. He had pain from the first but it did not extend down the arm. As he re-
covered from the pneumonia the hand and arm remained weak and this condition has not improved.
Examination showed pain on deep pressure in the axilla, but not to any degree over the nerves of the upper or lower arm. The right arm in general was about half an inch less in circumference than the left at various points. There was no shoulder- joint involvement nor manifest disturbance of the upper arm. There was no objective disorder of sensation,
but a distinct subjective sense of numbness in the ulnar distribution. The arm reflexes were retained. Atrophy was marked in the hand, both of the interossei and thenar muscles.
Extension of the hand was possible, but the grasp was very weak, as were the ulnar movements (ab- and adduction of the fingers; extension of the terminal phalanges). The little finger and thumb could not be approximated. Electrical examination showed a slow galvanic response, AnC = CaC, with reduced faradic reaction; partial R. D.

Diagnosis: Brachial Plexus Neuritis

This case is presumably a Brachial Neuritis following an infectious process. It differs from Case 7 in that the brachial plexus is itself sensitive to pressure and the motor disturbances are much more conspicuous in the hand than the sensory. The extreme atrophy of the small muscles of the hand is suggestive of a progressive muscular atrophy of the spinal type, particularly since the objective disturbance of sensation in the hand is exceedingly slight. The electrical reactions are consistent with either condition. On the other hand, the tenderness over the brachial plexus, the fact that pain has been somewhat conspicuous in the history and the wholly unilateral character of the affection all point strongly to the probability of a neuritis of a degenerative type. Prognosis of such plexus neuropathy. If the supposition of a localized neuritis be correct, complete recovery is to be expected.

Treatment of Brachial Plexus Neuritis

In this case it is more important to treat the patient’s general condition than the local disturbance. Pains should be taken to prevent the possibility of finger contractures.
