Blood blisters on feet

Introduction Foaming on the feet is caused by the rupture of tissue cells caused by long-term intense friction of the local tissue on the feet, and then the blood bubbles on the feet are formed. You can observe it, check the blood routine, see if there is a possibility of hemangioma, pay attention to the adjustment observation of imaging, it is necessary to check CT, B-ultrasound. In general, you don't have to do too many checks, check for infections, check your body temperature, urine, sleep, diet, etc. You can use topical Chinese medicine.

Or a lower extremity vascular lesion caused by diabetes complications or a paresthesia or loss caused by neuropathy. Easy to merge infection, form ulcers, and blisters.

Differential diagnosis

Differential diagnosis of blood on the feet:

First, the blood bubble on the foot should be distinguished from the blood cells in other parts of the body:

1. Oral blood bubble: Oral ulcer, also known as "mouth sore", is a blood bubble that occurs on the oral mucosa. The size can range from rice to soybean, round or oval, and the ulcer surface is concave and concave around the mouth. Congestion can cause pain due to irritating food, usually one to two weeks can heal itself. The prevalence rate in the population is generally considered to be more than 10%, which can occur in men, women and children, and is most common among young people. Recurrent oral ulcer is a localized ulcerative ulcer of the oral mucosa characterized by periodic recurrence. It can heal itself and can occur in any part of the oral mucosa. In the mucous membranes of the lips, cheeks, soft palate or gums, single or multiple round or oval ulcers of different sizes occur, the surface is covered with gray or yellow pseudomembrane, the central depression, the boundary is clear, and the surrounding mucosa is red and micro Swelling, local burning pain is the main feature.

2, the surface of the skin often appears scattered in the size of the blood bubble: the surface of the skin often appears in different sizes of bloody vesicles is one of the symptoms of abdominal necrotizing fasciitis. The necrotizing of abdomal wall is a necrotic soft tissue infection that occurs in the abdominal wall. There are many kinds of pathogenic bacteria. The infection mainly involves the deep abdominal wall and superficial fascia, and it can also invade the skin, but it does not involve the muscle in the early stage. The disease can occur in any part of the abdominal wall (such as the anterior abdominal wall, lateral abdominal wall, groin area and posterior ventral wall), especially in abdominal trauma or surgical cutting (invasive) mouth and adjacent areas, but also for the buttocks, The infection of the perineum spreads, sometimes after a small stab wound or insect bite. Necrotizing fasciitis has a sharp onset, rapid progress, and a dangerous condition. Delayed diagnosis and treatment often lead to death.

Second, the blood bubble on the foot needs to be differentiated from the initial symptoms of the diabetic foot:

Initial diabetic foot symptoms: blisters and blisters on the soles of the feet or the back of the feet, often scald or frostbite, corns, etc., leading to frequent superficial injuries or ulcers in the feet, and redness and swelling, and less secretion of initial ulcers.
