Burning pain

Introduction Burning pain can be seen in burning neuralgia. Burning neuralgia refers to the main symptoms of severe burning pain in the area consistent with the scope of the injured nerve after a clear nerve injury, manifested as pain abnormalities (heteropathic pain), hyperalgesia, sympathetic dysfunction , blood flow disorders, abnormal sweating, bone and muscle atrophy, and sometimes chronic refractory pain syndrome showing edema changes.

Cause

Hyaluronic acid, acid mucopolysaccharide, mucin increased significantly, diffuse or localized deposition in the skin.

Clinical manifestations:

50% of patients developed onset within 24 hours of injury, the rest occurred within 1 month after injury, and a few occurred 2 months after injury. Sustained burning pain, or stabbing or knife-like pain.

The pain area is not necessarily clear. Usually at the nerve's tip. Injured limbs and skin almost all have allergies, do not dare to contact any object, accidentally collide, even if it is very light, it can make the pain worse. , light will escalate the pain, the sound of the door closing, the sound of metal falling, the footsteps of the floor, and even the flipping of the newspaper or the breeze blowing can induce severe pain. The patient himself does not dare to speak loudly, fear of light, and the sun and emotions can aggravate the condition. When the pain is severe, it can be seen that the patient is restless, sweating around the body, and dilated pupils. The patient's skin may be characterized by flushing, increased temperature, and sometimes manifested as dampness, sweating, bruising, dystrophies, hair loss, toenail distortion, and osteoporosis.

1, the disease usually occurs within 1 to 2 weeks after the injury.

2, with an unbearable persistent burning-like pain in the palm of the finger (toe) and the palm of the hand (foot), the range of pain is more extensive, but generally the area of the damaged nerve is more prominent. The affected limb is particularly sensitive. Any emotional, mental factors and slight external stimuli can promote the pain, affecting the patient's normal rest and eating. In order to relieve the pain, the patient often refuses the doctor's examination and is unwilling to contact with the outside world. Wrapped in cold water or wrapped in a cold towel, the affected limb is pale or bun, the temperature is lowered, the skin is smooth and thin, sweating is increased, the nails are bent and thickened, the hair is falling off, and sometimes herpes can occur.

3, the patient is extremely painful, fearful, nervous, often irritated, uneasy, and irritating. If the course of disease is longer, there may be disuse changes such as muscle atrophy, joint stiffness and osteoporosis.

4, the incidence: the ratio of men and women is 5:1, more common in 20 to 40 years old (very few children). The predilection sites are brachial plexus, sciatic nerve, median nerve, phrenic nerve, and finger nerve.

Differential diagnosis

The disease needs to be differentially diagnosed with the following diseases:

1, fistula syndrome: only the burning of the soles of the feet, to a lesser extent, does not spread to the proximal end of the limbs, calf pain only occasionally.

2, erythema limb pain: both feet at the same time, mainly for severe burning pain in the extremities, with paroxysmal vasodilatation, redness, increased skin temperature, does not spread to the proximal end of the limb.
