Diabetic blisters, also known as bullosis diabeticorum or diabetic bullae, are painless lesions that appear most commonly on the legs, feet and toes of diabetic patients, according to Healthline. The blisters can be up to 6 inches in size and normally appear in clusters. There is no known cause, but the blisters are more common among patients who do not have their blood sugar under control and patients with diabetic nerve damage.

To rule out a more serious skin condition, Healthline suggests consulting a dermatologist. If the blister is large, the doctor may drain some of the fluid to keep the skin intact and prevent accidental rupturing. To relieve itching, the doctor may prescribe a steroidal cream. Call your doctor immediately if you experience redness around the blister, pain, fever, swelling or warmth radiating from the lesion.

If you have diabetes, it is important to consistently inspect your skin for blisters and lesions, notes Healthline. To prevent blisters, examine your feet and legs every day, wear socks and shoes that aren't too tight, and apply sunscreen when out in the sun, as ultraviolet light can cause blisters in some patients.
