How Do I Know If My Foot Blister Is Infected?

All wounds where the skin breaks are painful. However, there are a few important signs which should help you judge whether your blister is infected. Watch out for the following signs:

  • The blister and the surrounding area are painful to touch.
  • The skin displays a reddish discoloration and feels tender.
  • There is pus formation, bleeding, and the blister emits a foul smell.
  • The skin is peeling, and the blister is not healing at all.

You need to visit a doctor immediately if the infection shows signs of spreading. If this has happened, you might notice you’ve developed chills or a fever and body ache.

How Can I Treat My Foot Blister at Home?

As with any open wound, cleaning is necessary. So, start by cleaning the blister before following through with any treatment.

  • Place the affected foot with the blister in warm water.
  • Gently clean/rinse the blister – ensure your hands are clean before doing this.
  • Mix 1-2 teaspoons of salt in some warm water and soak your feet in it for about 15-20 minutes – salt can help sanitize the wound and reduce pain.
  • If the blister is open and the outer skin is loose or flapping, cut it gently with medical scissors – make sure you don’t cut too close to the open wound.
  • Once the blister is clean, apply an over-the-counter topical antibiotic ointment to treat the infection.
  • You can take an anti-inflammatory pain killer to manage the pain.
  • You can continue doing this until the blister heals.
  • If you find the blister is not healing at all even after a week or so, please consult with a podiatrist as soon as possible.

Important – If you have a health condition such as diabetes or you suffer from poor circulation or any other serious chronic condition or infection, consult with your medical doctor and a podiatrist before trying home remedies.

Health Risks Associated With Infected Blisters

Even if you don’t have a health condition and find that your blister is not healing – please visit a professional foot and ankle specialist as soon as possible.

An untreated or infected blister can pose serious health risks. If the infection spreads, it could lead to cellulitis – a skin infection which, if left unchecked, can infect your lymph nodes.

The spread of infection could easily compromise your immune system leading to further complications.

What to Expect During a Doctor’s Visit?

When you visit a doctor for an infected blister, the doctor will put you on a course of antibiotics or antifungal medication to treat the infection.

If there is pus formation, the doctor will drain the blister first and treat it medically, which may also involve cutting away the loose skin and dead tissue.

Again, if the infection is very serious, a further lab exam might be needed to accurately diagnose the cause of infection – once the cause is accurately diagnosed, the doctor can recommend the correct treatment.
