Patients with diabetes who have had poor glycemic control for a long time can have damage to their peripheral nerves, and foot pain can be a sign of peripheral nerve damage, but the diagnosis of peripheral nerve damage is a diagnosis of exclusion, and requires the completion of lower extremity vascular ultrasound and other relevant tests to determine whether there is thrombosis, infection, or other causes of pain.
Diabetic patients have a poor immune system, and the more common infections are fungal infections that cause diabetic foot and skin infections that cause Daniosis.
Diabetic foot is mainly characterized by redness, swelling, heat, and pain in the local tissues, and in severe cases, the diabetic foot may show local wound ulceration.
Dangiosis is mainly a hemolytic streptococcus that causes superficial lymphadenitis through skin breakdown, which is characterized by marked redness, swelling, and clear boundaries.
Diabetes is also an important factor in thrombosis. Diabetic patients with sudden onset of acute swelling and pain in the lower extremities should also be alert to the formation of venous thrombosis in the lower extremities, which can be clearly diagnosed by improving vascular ultrasound of the lower extremities.
