Wounds that won't close: what to do
A wound that doesn't improve in two weeks is not "normal with age." It's a sign your body needs professional help.

Nearly 15% of Medicare beneficiaries live with chronic wounds, and a single diabetic foot ulcer episode can cost more than $10,000 in care (McKnight's, 2024; Value in Health / USC Schaeffer Center). The good news: caught early, most can be treated. Medicare and Medi-Cal cover medically necessary wound care; check the details with your plan.
What is a chronic wound?
It's a wound that doesn't follow the normal healing process and stays open for weeks or months. The most common are:
- Diabetic foot ulcer: appears in people with diabetes due to poor circulation and loss of feeling in the feet.
- Pressure ulcer (bedsore): forms where the body presses against a bed or chair for a long time.
- Venous and arterial ulcers: related to leg circulation problems.
⚠️ When to see a doctor right away
- The wound has a bad smell, pus, or spreading redness.
- You have a fever or pain is getting worse instead of better.
- The wound hasn't improved in 2 weeks or is getting bigger.
- You have diabetes and get a blister or cut on your foot, even if it looks small.
In these cases don't wait: an infection can spread fast.
Why won't it close?
Diabetes damages small blood vessels and nerves: less blood (and fewer defenses) reaches the wound, and you may not feel the damage. Constant pressure on the same area and smoking also slow healing.
Risk factors
- Having diabetes, especially with uncontrolled blood sugar.
- Older age or spending a lot of time in bed or a wheelchair.
- Poor circulation in legs and feet.
- Smoking.
What you can do
- Check your feet every day if you have diabetes, even between the toes.
- Don't walk barefoot, not even at home.
- Don't put home remedies on open wounds without medical guidance.
- Change position often if you spend a lot of time sitting or lying down.
- Keep your blood sugar under control: it helps wounds close more than anything.
Frequently asked questions
Is it normal for a wound to take months to close?
No. A wound that doesn't improve in a couple of weeks deserves a professional evaluation. The sooner it's treated, the simpler the treatment.
Do hydrogen peroxide or alcohol help?
They can irritate healthy tissue and delay healing. Clean with water and mild soap and ask a professional about proper care.
Do diabetic foot wounds always end in amputation?
No. Amputation is a possible complication of uncontrolled diabetes, not an inevitable outcome. Early care of any foot wound greatly reduces that risk.
