3 Reasons Why You Shouldn’t Ignore That Blister

Posted by on Thursday, July 11th, 2013


There are many ways to prevent blisters these days, with a wide range of insoles and shoe cushions available over-the-counter. Blisters are more than just unsightly and uncomfortable, Fox News warns in their article about “Six Health Threats You Can’t Ignore.” Here at our NYC Center for Podiatric Care and Sports Medicine, we see a lot of blisters that have caused tremendous trouble for their owners. Find out why!

Foot Infections

Every year, male patients end up in the hospital on IV antibiotics due to preventable foot infections. A blister creates an opening into the body that invites microbes like bacteria and fungus. Once inside, these pathogens wreak havoc on the body and cannot be stopped without antifungal or antibacterial medication. Athlete’s foot is one of the more common foot infections that may manifest as blisters on toes. Untreated toenail fungus can lead to complications such as: the loss of toenails, deformity, difficulty walking, foot ulcers and gangrene. Ciclopirox gel is a prescription medication that can work against both sources of infection, but the infection must be caught relatively early for it to be effective.

Skin Reactions

Sometimes blisters are not really blisters at all. Psoriasis, eczema, contact dermatitis and allergic reactions are commonly misdiagnosed as blisters. These itchy autoimmune disorders will often spread to other parts of the body and will require a different type of treatment from a dermatologist or podiatrist. Furthermore, that “blister” could be a tick burrowing into the foot (as pictured above), a bug bite, or a bee sting. While these are usually harmless, bites from certain types of spiders and ticks can be a real health danger.

Diabetic Ulcers

Diabetics should have every cut and blister looked at by a podiatrist. Since diabetics suffer from poor circulation, the smallest wound could take a very long time to heal – or, in some cases, may not heal at all without advanced treatment. The longer an open wound is present, the more opportunity there is for infection to develop. There are literally hundreds of types of microbes on our feet – and some of these are harmful to our health. According to the Infectious Diseases Society of America, “Nearly 80 percent of all nontraumatic amputations occur in people with diabetes – and 85 percent of those begin with a foot ulcer.” Worse yet, almost half the people who require amputation die within five years. That is a chance you do not want to take!
