A diabetic foot ulcer is an open sore or wound that develops on the foot in people with diabetes, often caused by poor circulation and nerve damage that reduce feeling in the feet and slow healing. These ulcers can begin from a small cut, blister, or pressure spot and may become serious if not treated promptly. Symptoms can include redness, swelling, drainage, or an unpleasant odor, though some patients may not feel pain. Early treatment, daily foot checks, good blood sugar control, and proper footwear are important to help prevent complications and promote healing.

A pressure ulcer, also known as a bed sore or pressure injury, is an area of damaged skin and tissue caused by prolonged pressure on the skin, most commonly over bony areas such as the heels, hips, tailbone, or elbows. These wounds often develop in people who have limited mobility or spend long periods sitting or lying in one position. Symptoms may include redness, pain, skin breakdown, drainage, or open sores. Early treatment, regular repositioning, proper nutrition, skin care, and pressure-relieving devices are important to promote healing and prevent complications.

A venous leg ulcer is an open sore that develops on the lower leg or ankle due to poor blood flow in the veins, most commonly in people with chronic venous insufficiency. When blood does not circulate properly back to the heart, pressure builds in the veins and can damage the skin, leading to a slow-healing wound. Venous leg ulcers may cause swelling, aching, skin discoloration, drainage, or itching around the affected area. Early treatment, compression therapy, leg elevation, regular exercise, and proper wound care are important to improve healing and help prevent recurrence.

A post-surgical wound is a wound or incision that remains after a surgical procedure as the body heals. While most surgical wounds heal normally, some may heal slowly or develop complications such as infection, drainage, swelling, or reopening of the incision. Factors such as diabetes, poor circulation, smoking, or certain medical conditions can affect healing. Proper wound care, keeping the area clean and protected, following post-operative instructions, and monitoring for signs of infection are important to support healing and prevent complications.

A traumatic wound is an injury to the skin and underlying tissue caused by an external force such as a cut, skin tear, fall, burn, or injury from an accident. These wounds can range from minor skin tears to deep injuries involving muscles, tendons, or bones. Symptoms may include pain, bleeding, swelling, bruising, or drainage. Proper cleaning, wound care, and medical treatment are important to prevent infection, promote healing, and reduce the risk of complications.

A chronic non-healing wound is an open sore, injury, or ulcer that fails to progress through the normal, orderly stages of healing within a standard timeframe, typically lasting for more than four to six weeks. These wounds often occur when underlying medical conditions, such as diabetes, severe vascular disease, prolonged immobility, or chronic inflammation, interfere with the body's natural reparative processes. Symptoms can include persistent pain, swelling, skin discoloration, foul-smelling drainage, or necrotic (dead) tissue within the wound bed. Specialized medical intervention, advanced wound care therapies, infection control, and addressing the root systemic causes are required to stimulate healing and prevent severe complications like deep tissue infections or amputation.
