Redness, swelling and pain in both feet

Introduction Caused by erythematous limb pain disease, under certain incentives, paroxysmal clinical manifestations of bipedal redness, swelling, heat, pain, etc., is a clinical feature of erythematous limb pain. Erythromorphic erythromelalgia is an autoimmune disease characterized by paroxysmal vasodilatation of the distal extremities, elevated skin temperature, flushing of the skin, and intense burning pain. Erythromelalgia is an unexplained peripheral vasomotor dysfunction. The clinical features are red, swollen, painful, and hot skin of the extremities. It occurs in both feet. The youngest age is 8 years old. The 52-year-old. More common in young adults, it is a rare disease.

Cause

The etiology and pathogenesis of erythematous limb pain is not clear, and it is generally considered to be divided into three types:

1. Primary erythematous limb pain: the cause is unknown, may be related to autonomic or vascular nerve center dysfunction, skin is allergic to warmth and some hyperthermia in the blood, a small number of patients have family factors.

2. Secondary erythematous limb pain: secondary to certain diseases such as diabetes, polycythemia vera, pernicious anemia, gout, light cellulitis, rheumatoid arthritis, systemic lupus erythematosus, thromboangiitis Vasculitis, carbon monoxide poisoning, heart failure, hypertension, etc.

3. Idiopathic erythema limb pain: the pathogenic factors of this disease may not be single but the result of a combination of many factors. The first is related to the sudden change in temperature and cold stimulation. Adolescent students are prone to this disease, indicating that the autonomic and endocrine system instability during puberty is poorly adaptable to external environmental changes, and whether it is related to certain biological pathogenic factors or nutritional deficiencies is still uncertain.

an examination

Platelet count (PLT) red blood cell count (RBC)

Blood, urine routine

There are often thrombocytosis and erythrocytosis.

2. Blood biochemistry

Blood biochemical tests and cerebrospinal fluid routine examinations are mostly non-specific, but secondary red hot limb pain is associated with the primary disease. Drug and toxicant detection have differential diagnosis significance.

3.B super, color ultrasound.

4. Microcirculation inspection

It can be seen that the microvascular of the extremity is enhanced by the warming reaction, the capillary pressure is increased, the lumen is obviously dilated, and the acne capillary is blurred.

5. Skin critical temperature test

Soak your hands or feet in water at 32-36 ° C. If symptoms appear or are aggravated, they are positive.
