Purple black after yellow blister on toe skin

Introduction One of the symptoms of dislocation is the purple and yellow foam on the skin of the toes. Dislocation refers to a chronic peripheral vascular disease in which the extremities of the extremities are necrotic and the sputum is broken. Occurs at the end of the extremities, more common in the lower extremities, also known as dislocation. Mainly due to temper temper, lack of kidney yang, plus external cold, cold and wet evil invasion and disease. The temper is not healthy, the lack of metaplasia, the deficiency of qi and blood, the internal organs can not be raised; the outside can not be raised. Insufficient spleen and kidney yang, can not warm the limbs, regain the evil of cold and dampness, then the blood stasis, the meridian block, the pain is not, the limbs are not full of blood, lost in the support of the flesh and blood, necrosis.

Cause

Mainly due to temper temper, lack of kidney yang, plus external cold, cold and wet evil invasion and disease. The temper is not healthy, the lack of metaplasia, the deficiency of qi and blood, the internal organs can not be raised; the outside can not be raised. Insufficient spleen and kidney yang, can not warm the limbs, regain the evil of cold and dampness, then the blood stasis, the meridian block, the pain is not, the limbs are not full of blood, lost in the support of the flesh and blood, necrosis. If the cold evil has a long history, then the stagnation and heat, hot and humid immersion, then suffering from toe (referring to) red swelling and pus. Heat evil yin, long-term illness can cause yin and blood deficiency, limb dystrophy, dry and shrinking. The occurrence of this disease is related to long-term smoking, trauma and other factors. In short, the occurrence of this disease is based on spleen and kidney deficiency, cold and wet trauma as the standard, and qi stagnation, meridian obstruction is its main pathogenesis.

Limb blood flow diagram

1. The vast majority occur in men, mostly between the ages of 25 and 40.

2. Occurs at the end of the extremities, the lower extremities are more common.

3. Before the onset, there were smoking, cold, and history of calf trauma.

4. The initial limbs are heavy, cold, numb, acupuncture-like pain in the toes, twitching pain in the calf muscles, and intermittent claudication. After the cold of the hands and feet, the pain increased, and the dorsal artery pulsation weakened. Or accompanied by superficial vein migration thrombophlebitis, and some have this performance before the onset.

5. In the mid-term (longer to mid-term course), the local skin is cold. When the affected limb is raised, the skin color is pale, the drooping is dark red, and the pain turns into persistence. Difficulties in walking, restless nights, muscles of the affected limbs gradually shrink (may also have edema), the skin of the feet is atrophied, the hairs fall off, the toenails thicken, and the miliary yellow spots may appear repeatedly, and the dorsal artery pulsation disappears or weakens.

6. The skin color of the affected limbs is dark red, like cooked red dates, yellow foam on the skin, gradual black, invasive spread; even five-toed pass, spread to the back of the foot, the meat is wilted, dry necrosis Broken rot, wounds purple black blood, wounds are not fresh, the smell is very stinky, the pain is severe, such as soup burning, not sleeping all night, often have to knees and massage to sit, the dorsal artery pulsation disappears. Rotten spread, five-toed pass, up to the back of the foot, falling off from the knot, and even the cheekbones, long time unhealed, sore mouth is difficult to confine.

7. Positive limb position test. The patient was placed in a supine position and the lower limbs were raised (45°) for 3 minutes. The skin of the foot quickly turned pale, accompanied by numbness and coldness, and the pain was aggravated. Then let the patient sit up, the affected limb is drooping, and the color of the skin of the foot is slow to recover, which may be tidal red, purple or plaque-like purpura. This is positive, indicating that the arterial spasm or obstruction has blood circulation disorder, arterial blood. Insufficient traffic.

Differential diagnosis

The blood bubble on the foot: the foam on the foot is caused by the rupture of the tissue cells caused by the long-term intense friction of the local tissue on the foot, and then the blood bubble on the foot is formed seriously. More common in the cold season, more common in men aged 20 to 40; often first side of the lower limbs, and then involved the contralateral side, a small number of patients can involve the upper limbs; patients have a history of cold, damp, smoke, trauma and other diseases. Atherosclerotic occlusive disease is more common in the elderly (over 50 years old). According to the disease development process.

Should be distinguished from occlusive atherosclerosis. The latter is over 40 years old, often with hypertension, diabetes, hyperlipidemia and coronary atherosclerotic heart disease. Often involved in the large and middle arteries, the course of disease is developing rapidly. X-ray or vascular color Doppler ultrasonography may indicate calcification in the arterial wall of the affected limb.
