Visceral pain is pain that results from the activation of nociceptors of the thoracic, pelvic, or abdominal viscera (organs). Visceral structures are highly sensitive to distension (stretch), ischemia and inflammation , but relatively insensitive to other stimuli that normally evoke pain such as cutting or burning.
Nerve compression syndrome, or compression neuropathy, or nerve entrapment syndrome, is a medical condition caused by chronic, direct pressure on a peripheral nerve. [1] It is known colloquially as a trapped nerve, though this may also refer to nerve root compression (by a herniated disc, for example).
Thoracic splanchnic nerves are splanchnic nerves that arise from the sympathetic trunk in the thorax and travel inferiorly to provide sympathetic supply to the abdomen. The nerves contain preganglionic sympathetic fibers and general visceral afferent fibers.
The neurogenic type is the most common and presents with pain, weakness, paraesthesia, and occasionally loss of muscle at the base of the thumb. [1] [2] The venous type results in swelling, pain, and possibly a bluish coloration of the arm. [2] The arterial type results in pain, coldness, and pallor of the arm. [2]
' pain receptor ') is a sensory neuron that responds to damaging or potentially damaging stimuli by sending "possible threat" signals [1] [2] [3] to the spinal cord and the brain. The brain creates the sensation of pain to direct attention to the body part, so the threat can be mitigated; this process is called nociception .
Activity exercise-whether one is able to do daily activities normally without any problem, self care activities Sleep rest-do they have hypersomnia, insomnia, do they have normal sleeping patterns Cognitive-perceptual-assessment of neurological function is done to assess, check the person's ability to comprehend information
The vagus nerve (CN X) does not participate in these cranial ganglia as most of its parasympathetic fibers are destined for a broad array of ganglia on or near thoracic viscera (esophagus, trachea, heart, lungs) and abdominal viscera (stomach, pancreas, liver, kidneys, small intestine, and about half of the large intestine).
Management of chest pain is based on the underlying cause. [1] Initial treatment often includes the medications aspirin and nitroglycerin. [1] [4] The response to treatment does not usually indicate whether the pain is heart-related. [1] When the cause is unclear, the person may be referred for further evaluation. [3]
