Inflammation of a nerve:
a. neuropathy
b. neuralgia
c. sciatica
d. neuritis

The correct answer is Neuritis (D).

Explanation:

Neuritis is the inflamation of a nerve and its ramifications, usually accompanied by pain, muscular atrophy and other pathological phenomena.

It can be caused by injuries, infections or autoimmune diseases. The most characteristic symptoms of neuritis are: pain, tenderness, numbness, hypersensitivity, lack of strenght, circulation disorders and pain in the affected region. This usually has a burning or stabbing character, being especially uncomfortable when intercostal neuritis occurs, since the pain worsens with respiratory movements.

Since there are many nerves in the body and everyone can suffer from neuritis, the causes of this happening can be varied. For example, a wound or eating deficiencies can cause neuritis. Other causes that can cause neuritis include alcoholism, as well as a lack of vitamin B.
