Vasomotor disorders of the extremities

Vasomotor disorders of the extremities can cause symptoms such as headache, purple or red extremities. Diagnosis and early detection of this condition is important for its treatment.

Cyanosis of the extremities is bilateral symmetrical cyanosis, seen on the skin of the hands and feet, forearms and lower legs. It is associated with arterial spasm with dilatation of the subpapillary venous plexus of the skin. From there, the deoxygenated blood circulation slows down. This condition is aggravated when the weather turns cold and during the hot season it may not go away completely.
Cyanosis can occur in both men and women, usually in young adults in their 20s, progressing with age and pregnancy. It may be accompanied by symptoms such as cold, mild swelling, and cyanosis in some areas of the body. The patient does not have pain, nutritional disorders or disability, and the peripheral pulse is still normal. Therefore, patients do not need to worry too much, just pay attention to dress warm when it is cold.

2.1 Causes This is a bilateral paroxysmal vasodilatation disorder caused by dilation of small arteries in the hands and feet. Redness, idiopathic headache (unknown cause) occurs in normal adults, rarely in children, the incidence of men - women is similar.
Redness, headache secondary to extremity may be seen in patients with erythrocytosis, gout, hypertension, scleroderma, rheumatoid arthritis, systemic lupus erythematosus, diabetes mellitus, venous insufficiency, ... or neuropathy. More rarely, the condition may be related to the use of certain medications (nifedipine, bromocriptine) or to a rare genetic pattern that begins at birth or in childhood. As for red, random extremity headache is a benign form.
2.2 Symptoms The main symptom of the patient is a burning pain in both extremities, lasting from a few minutes to hours. Initially, the patient usually has pain in the palm or the soles of the feet. As the disease progresses, the pain spreads to the entire extremities.

Red, limb headache due to limb vasomotor disorders occurring after a vasodilating stimulus such as exercise or a warm environment (29 - 32°C), especially at night when the patient sleeps with a warm blanket . In addition to pain and redness of the extremities, the patient may experience heat or cyanosis of the extremities.
2.3 Diagnosis and treatment Diagnosis of red, painful extremities caused by limb vasomotor disorders is based on symptoms and clinical examination. The patient may be ordered to have a complete blood count test repeated many times (because this is an early manifestation of a myeloproliferative disorder). At the same time, it is necessary to make a differential diagnosis with nutritional disorders after trauma, peripheral neuropathy, shoulder-hand syndrome,...
The patient can cool the affected parts, rest Rest, raise spending to overcome this situation. For primary red, extremity headache, the patient may be prescribed gabapentin. In addition, when there is redness, headache, the patient can take aspirin 650mg every 4-6 hours to relieve pain. At the same time, patients should avoid living in too warm environments. In severe cases, if medical treatment fails, the patient may need to cut peripheral nerves to relieve pain.
