Clinical Information

• Brachial Plexus Neuritis-. a syndrome associated with inflammation of the brachial plexus. clinical features include severe pain in the shoulder region which may be accompanied by muscle weakness and loss of sensation in the upper extremity. this condition may be associated with virus diseases; immunization; surgery; heroin use (see heroin dependence); and other conditions. the term brachial neuralgia generally refers to pain associated with brachial plexus injury. (from adams et al., principles of neurology, 6th ed, pp1355-6)
• Cluster Headache-. a primary headache disorder that is characterized by severe, strictly unilateral pain which is orbital, supraorbital, temporal or in any combination of these sites, lasting 15-180 min. occurring 1 to 8 times a day. the attacks are associated with one or more of the following, all of which are ipsilateral: conjunctival injection, lacrimation, nasal congestion, rhinorrhea, facial sweating, eyelid edema, and miosis. (international classification of headache disorders, 2nd ed. cephalalgia 2004: suppl 1)
• Diabetic Neuropathies-. peripheral, autonomic, and cranial nerve disorders that are associated with diabetes mellitus. these conditions usually result from diabetic microvascular injury involving small blood vessels that supply nerves (vasa nervorum). relatively common conditions which may be associated with diabetic neuropathy include third nerve palsy (see oculomotor nerve diseases); mononeuropathy; mononeuropathy multiplex; diabetic amyotrophy; a painful polyneuropathy; autonomic neuropathy; and thoracoabdominal neuropathy. (from adams et al., principles of neurology, 6th ed, p1325)
• Facial Neuralgia-. neuralgic syndromes which feature chronic or recurrent facial pain as the primary manifestation of disease. disorders of the trigeminal and facial nerves are frequently associated with these conditions.
• Glossopharyngeal Nerve Diseases-. diseases of the ninth cranial (glossopharyngeal) nerve or its nuclei in the medulla. the nerve may be injured by diseases affecting the lower brain stem, floor of the posterior fossa, jugular foramen, or the nerve's extracranial course. clinical manifestations include loss of sensation from the pharynx, decreased salivation, and syncope. glossopharyngeal neuralgia refers to a condition that features recurrent unilateral sharp pain in the tongue, angle of the jaw, external auditory meatus and throat that may be associated with syncope. episodes may be triggered by cough, sneeze, swallowing, or pressure on the tragus of the ear. (adams et al., principles of neurology, 6th ed, p1390)
• Herpes Zoster Oticus-. a syndrome characterized by facial palsy in association with a herpetic eruption of the external auditory meatus. this may occasionally be associated with tinnitus, vertigo, deafness, severe otalgia, and inflammation of the pinna. the condition is caused by reactivation of a latent herpesvirus 3, human infection which causes inflammation of the facial and vestibular nerves, and may occasionally involve additional cranial nerves. (from adams et al., principles of neurology, 6th ed, p757)
• Hypoglossal Nerve Diseases-. diseases of the twelfth cranial (hypoglossal) nerve or nuclei. the nuclei and fascicles of the nerve are located in the medulla, and the nerve exits the skull via the hypoglossal foramen and innervates the muscles of the tongue. lower brain stem diseases, including ischemia and motor neuron diseases may affect the nuclei or nerve fascicles. the nerve may also be injured by diseases of the posterior fossa or skull base. clinical manifestations include unilateral weakness of tongue musculature and lingual dysarthria, with deviation of the tongue towards the side of weakness upon attempted protrusion.
• Median Neuropathy-. disease involving the median nerve, from its origin at the brachial plexus to its termination in the hand. clinical features include weakness of wrist and finger flexion, forearm pronation, thenar abduction, and loss of sensation over the lateral palm, first three fingers, and radial half of the ring finger. common sites of injury include the elbow, where the nerve passes through the two heads of the pronator teres muscle (pronator syndrome) and in the carpal tunnel (carpal tunnel syndrome).
• Morton Neuroma-. a nerve inflammation in the foot caused by chronic compression of the plantar nerve between the metatarsal bones.
• Neuralgia-. intense or aching pain that occurs along the course or distribution of a peripheral or cranial nerve.
• Neuralgia, Postherpetic-. pain in nerves, frequently involving facial skin, resulting from the activation the latent varicella-zoster virus (herpesvirus 3, human). the two forms of the condition preceding the pain are herpes zoster oticus; and herpes zoster ophthalmicus. following the healing of the rashes and blisters, the pain sometimes persists.
• Pudendal Neuralgia-. pain associated with a damaged pudendal nerve. clinical features may include positional pain with sitting in the perineal and genital areas, sexual dysfunction and fecal incontinence and urinary incontinence.
• Sciatic Neuropathy-. disease or damage involving the sciatic nerve, which divides into the peroneal nerve and tibial nerve (see also peroneal neuropathies and tibial neuropathy). clinical manifestations may include sciatica or pain localized to the hip, paresis or paralysis of posterior thigh muscles and muscles innervated by the peroneal and tibial nerves, and sensory loss involving the lateral and posterior thigh, posterior and lateral leg, and sole of the foot. the sciatic nerve may be affected by trauma; ischemia; collagen diseases; and other conditions. (from adams et al., principles of neurology, 6th ed, p1363)
• Sciatica-. a condition characterized by pain radiating from the back into the buttock and posterior/lateral aspects of the leg. sciatica may be a manifestation of sciatic neuropathy; radiculopathy (involving the spinal nerve roots; l4, l5, s1, or s2, often associated with intervertebral disk displacement); or lesions of the cauda equina.
• Trigeminal Neuralgia-. a syndrome characterized by recurrent episodes of excruciating pain lasting several seconds or longer in the sensory distribution of the trigeminal nerve. pain may be initiated by stimulation of trigger points on the face, lips, or gums or by movement of facial muscles or chewing. associated conditions include multiple sclerosis, vascular anomalies, aneurysms, and neoplasms. (adams et al., principles of neurology, 6th ed, p187)
• Facial Pain-. pain in the facial region including orofacial pain and craniofacial pain. associated conditions include local inflammatory and neoplastic disorders and neuralgic syndromes involving the trigeminal, facial, and glossopharyngeal nerves. conditions which feature recurrent or persistent facial pain as the primary manifestation of disease are referred to as facial pain syndromes.
• Syncope-. a transient loss of consciousness and postural tone caused by diminished blood flow to the brain (i.e., brain ischemia). presyncope refers to the sensation of lightheadedness and loss of strength that precedes a syncopal event or accompanies an incomplete syncope. (from adams et al., principles of neurology, 6th ed, pp367-9)
• Motor Neuron Disease-. diseases characterized by a selective degeneration of the motor neurons of the spinal cord, brainstem, or motor cortex. clinical subtypes are distinguished by the major site of degeneration. in amyotrophic lateral sclerosis there is involvement of upper, lower, and brainstem motor neurons. in progressive muscular atrophy and related syndromes (see muscular atrophy, spinal) the motor neurons in the spinal cord are primarily affected. with progressive bulbar palsy (bulbar palsy, progressive), the initial degeneration occurs in the brainstem. in primary lateral sclerosis, the cortical neurons are affected in isolation. (adams et al., principles of neurology, 6th ed, p1089)
• Metatarsal Bones-. the five long bones of the metatarsus, articulating with the tarsal bones proximally and the phalanges of toes distally.

Pain

Pain is a signal in your nervous system that something may be wrong. It is an unpleasant feeling, such as a prick, tingle, sting, burn, or ache. Pain may be sharp or dull. It may come and go, or it may be constant. You may feel pain in one area of your body, such as your back, abdomen, chest, pelvis, or you may feel pain all over.

Pain can be helpful in diagnosing a problem. If you never felt pain, you might seriously hurt yourself without knowing it, or you might not realize you have a medical problem that needs treatment.

There are two types of pain: acute and chronic. Acute pain usually comes on suddenly, because of a disease, injury, or inflammation. It can often be diagnosed and treated. It usually goes away, though sometimes it can turn into chronic pain. Chronic pain lasts for a long time, and can cause severe problems.

Pain is not always curable, but there are many ways to treat it. Treatment depends on the cause and type of pain. There are drug treatments, including pain relievers. There are also non-drug treatments, such as acupuncture, physical therapy, and sometimes surgery.

Peripheral Nerve Disorders

Your peripheral nerves are the ones outside your brain and spinal cord. Like static on a telephone line, peripheral nerve disorders distort or interrupt the messages between the brain and the rest of the body.

There are more than 100 kinds of peripheral nerve disorders. They can affect one nerve or many nerves. Some are the result of other diseases, like diabetic nerve problems. Others, like Guillain-Barre syndrome, happen after a virus infection. Still others are from nerve compression, like carpal tunnel syndrome or thoracic outlet syndrome. In some cases, like complex regional pain syndrome and brachial plexus injuries, the problem begins after an injury. Some people are born with peripheral nerve disorders.

Symptoms often start gradually, and then get worse. They include :

• Numbness
• Pain
• Burning or tingling
• Muscle weakness
• Sensitivity to touch

Treatment aims to treat any underlying problem, reduce pain and control symptoms.
