For many people, a blister may not be a serious concern. Blisters are small, fluid-filled sacs that develop due to friction or pressure on the skin. Some blisters go away on their own without any problems, but for those with diabetes, a blister can turn into a dangerous problem if the wound becomes infected. Blisters can become significant wounds

Signs of Infection

If you notice a blister on your foot or toe that has broken open, it’s possible for bacteria to get inside and cause an infection. And while those who are diabetic must be especially careful to watch for blisters, everyone is at risk for a blister to become infected.

Signs of Infection  

  • Pain or swelling that worsens over time
  • Redness around the area of the blister
  • Fluid oozing from the blister that is not clear and forms a yellow or green crust on the area
  • Tenderness or warmth

If an open blister is not treated promptly, an infection can develop and spread to surrounding tissue or bone. If the infection cannot be stopped, amputation is often the only option to prevent death.

Blister Treatment Options

Many blisters heal on their own and do not require further treatment. For those with diabetes or other conditions that can cause a wound to heal slowly or not at all, treating a blister at its earliest stage can prevent more serious, dangerous complications. That’s why it’s critical to see a podiatrist immediately.

A podiatrist will examine the wound and determine treatment based on your specific needs. If the blister needs to be drained, they will use a sterile tool. Never attempt to pop or drain a blister at home, and anyone with diabetes should take extra care. Blisters can often go undetected, become infected, and lead to a diabetic foot ulcer.

Blister Treatment Options

  • Cleaning and keeping the wound area dry
  • Applying a dressing or padding over the area of the wound
  • Keeping pressure off the area
  • Avoiding wearing shoes that rub the area of the blister
