In some cases, athlete’s foot can lead to complications.

Mild complications can include an allergic reaction to the fungus, which can lead to blistering on the feet or hands. It’s also possible for the fungal infection to return even after being treated.

A secondary bacterial infection can develop if blisters are filled with pus. This can lead to more severe complications. Signs of a bacterial infection include:

While uncommon, bacterial infections can spread to the lymphatic system and infect thelymph nodes.

Do Not Pop BlistersPopping blisters is not recommended. The bubble itself is a layer that protects against infection. Once the barrier is removed, the wound is exposed and can become infected. If a blister bursts on its own, do not peel off any dead skin.

Summary

A Word From Verywell

Athlete’s foot can be painful and uncomfortable. If you experience blisters from athlete’s foot, consider trying one of the many antifungal medications available for purchase over the counter, without a prescription. Don’t hesitate to reach out to a healthcare provider to discuss the best option for you, or when more serious intervention may be needed.

Blisters that appear on the sole or instep of your feet may be a symptom of athlete’s foot. You should never pop an athlete’s foot blister, as that removes the protective barrier, which will make it more likely to become infected.
