What causes venous pain?

There are many reasons for venous pain. It may be caused by vasculitis, which is a relatively serious disease. If you suspect this is the case, you should go to a regular hospital for examination in time to find out the specific cause and then treat it symptomatically. In daily life, you should avoid fatigue and pay attention to adequate rest. It is best not to eat spicy and irritating foods. You must pay attention to a light diet, eat more fresh fruits and vegetables, and drink plenty of water.

Causes

It is currently believed that this disease is caused by occlusion of small arteries due to spasm and thrombosis, resulting in local ischemia. Half of them are accompanied by Raynaud's phenomenon, which is more common in men and smokers. Smoking is closely related to the course and prognosis of this disease.

Clinical manifestations

This disease is more common in young and middle-aged people, and is prone to occur in the lower limbs. The affected limb shows temporary or persistent pallor, cyanosis, burning and tingling. The skin turns red when the affected limb is hanging and turns white when it is raised. It is followed by numbness of the toes and pain in the calf muscles. The pain is stimulated when walking and disappears when resting. Superficial phlebitis and edema often occur in the calf. During the examination, it was found that the dorsalis pedis artery pulse was weakened or disappeared. As the disease progresses, intermittent claudication and Raynaud's phenomenon may occur, pain may intensify at night, the toes may become extremely painful, the skin may become cyanotic, and then the toe tips may ulcerate or become gangrenous and turn black, gradually spreading to the proximal end.

treat

1. Drug treatment (1) Dextran-40: Dextran with a molecular weight of 5,000 to 20,000 is administered by intravenous drip. Long-term use may cause bleeding and it is not suitable for patients in the acute development stage or those with ulcer gangrene and secondary infection. (2) Vasodilators include tolazoline hydrochloride, niacin, and benzylamine hydrochloride. (3) Antibiotics: For patients with local and systemic infections, appropriate antibiotics should be selected for treatment. (4) Glucocorticoids may be considered in the acute phase of the disease, with daily oral prednisone or intravenous hydrocortisone. (5) Painkillers: For patients with significant pain, various analgesics can be used, or procaine acupuncture injection, intravenous blockade or femoral artery periartery blockade, or even lumbar sympathetic ganglion block or epidural anesthesia can be performed. (6) Local treatment: For dry gangrene, sterile bandage can be used to prevent infection, and for ulcers, Kangfuxin dressing can be applied externally. 2. Surgical treatment: For patients who have not responded to non-surgical treatment, lumbar sympathectomy, great saphenous vein graft bypass or arterial thromboendarterectomy can be performed. After the boundaries of extremity necrosis are limited, the wound is expanded and the necrotic tissue is removed under sterile conditions. For those who have developed finger (toe) gangrene, finger (toe) amputation should be considered.
