Toenail Fungal Infection (Toenail Fungus)
Medical Considerations for Toenail Fungal Infection
As noted earlier, people with diabetes and circulatory conditions are at increased risk for toenail fungal infections. In these individuals, an untreated infection can spread to the skin and cause blisters, lesions, open sores, allergic reactions due to the release of proteins into the bloodstream, or cellulitis, a potentially serious bacterial skin infection.
People with diabetes who have toenail fungus should see their doctor. Always talk to your doctor if you have soreness, pain, redness, swelling or other indications of foot problems that persist for more than a few days.
