Bedsore develops when blood supply to the skin is cut off for more than 2 to 3 hours. As the skin dries, bedsore first starts as a red, painful area, which eventually turns purple. If it is left untreated, the skin can break open and the area can become infected. Being bedridden, unconscious, unable to sense pain, or immobile increases the risk that bedsores will develop. The risk increases if the person is not turned, positioned correctly, or provided with proper nutrition and skincare. People with diabetes, circulation problems, and malnutrition are at higher risk.
Signs and symptoms:
Symptoms of a pressure sore include:
- Color changes: If discoloration does not disappear after removing the pressure for 10–30 minutes, this may indicate that a sore is forming.
- Texture changes: The area may feel hard or spongy and warm.
- Broken skin: There may be a shallow, open sore with fluid or pus in it. The wound may extend into the deeper layers of tissue.
- Infection: Signs include a change in color or sensation around the edge of the sore, the presence of more pus, green or black tissue around the sore, and a fever.
When to see a doctor?
If you notice warning signs of bedsore, change your position to relieve the pressure on the area. If you don't see improvement in 24 to 48 hours, contact your doctor. Seek immediate medical care if you show signs of infection, such as a fever, drainage from a sore, a sore that smells bad, or increased redness, warmth, or swelling around a sore.
see a doctor when you think you have symptoms of asthma and for its treatment and monitoring.
