Diabetic blisters are a relatively rare symptom of diabetes. These blisters can pop up for a variety of reasons, and experiencing them for the first time is scary. Fortunately, the blisters themselves typically heal in two to five weeks without intervention. That leaves you and your doctor managing the symptoms and warding off potential infection.

Take Precautions


This is one of the best daily practices you can have as a diabetic. By checking the skin all over your body, you know if something has changed. This is especially important if you have diabetic neuropathy, which sometimes happens in the feet. If there is something different, you can seek treatment before complications occur.


One of the biggest changes you can make before you get diabetic blisters is your shoes and socks. By wearing properly fitted shoes and socks, you reduce the irritation to your skin. If you wear them all the time, you can also avoid small skin injuries. This, in turn, helps your feet stay healthy.

Other Precautions

Some diabetics are sensitive to UV radiation, which in turn causes diabetic blisters and discomfort. Limiting sun exposure and applying sunscreen is a fantastic way for you to manage this risk.

Sometimes, diabetic blisters and lesions are the results of Candida albicans. This fungal infection risk can be managed by ensuring your skin remains clean and dry as much as possible. Your doctor may also assign you a regime if you have repeat problems.

Over the Counter

The important thing with your diabetic blisters is managing the secondary infection risk. An antibiotic cream can help do this. However, signs of an actual infection like redness, fever, warmth, swelling, or pain mean its time to see a doctor.


One of the best ways to manage diabetic blisters once they appear is bandaging. You do not want a blister to burst accidently since this can lead to an infection. By protecting the diabetic blisters, you’re ensuring they have time to heal as well as keeping them dry and clean.

Saline Compresses

Many people experience no pain with their diabetic blisters, but you may experience some itchiness. Since scratching would break the blister, it is best to apply saline compresses to reduce the sensation. Normal saline is available at most drug stores, and you can make your own providing you keep the process as sterile as possible.

Steroid Approach

In order to take the steroid approach to your diabetic blisters, you need to see your doctor. If they feel it is necessary to speed up healing, you will be given a prescription to use as directed. Applying steroids to diabetic blisters should yield changes within a few days, so check back with your doctor.

See a Doctor to Puncture

Sometimes, your diabetic blisters are as large as six inches. Other times, you get a cluster of them. At that point, your doctor may decide to puncture the blisters to reduce infection risks while leaving the blister roof intact. You should never puncture your own diabetic blisters, as this can result in complications.
