Can Yeast Infections Cause Blisters?

Yeast sores can occur over time due to other skin conditions triggered by the yeast infection. A rash can occur from the yeast infection that can then form sores or blisters. If you've developed sores from a rash attributable to your yeast infection, you should contact your doctor for treatment.

What do yeast sores look like?

Superficial candidal skin infections appear as a red flat rash with sharp, scalloped edges. Smaller patches of similar-appearing rash, known as "satellite lesions" or "satellite pustules," are usually nearby. These rashes may be hot, itchy, or painful. Intertrigo appears as softened red skin in body fold areas.

How long do yeast infection sores last?

Mild yeast infections may clear up in as few as three days. Sometimes, they don't even require treatment. But moderate to severe infections may take one to two weeks to clear.
