A foot ulcer is a deep open wound, usually on the bottom of the foot that can be slow or difficult to heal. If you’ve lost feeling in your feet from neuropathy you might not feel it if you have a cut or blister. Continuing to walk on even a minor injury can irritate the skin, causing it to break down and develop into an ulcer. This is a serious condition and immediate medical care is required to prevent the spread of infection. The good news is by taking good care of your feet you can prevent foot ulcers from developing in the first place. Check your feet every day for blisters, cuts and sores and call your health care provider if you notice anything that isn’t healing right. Always wear comfortable, well-fitting shoes and avoid going barefoot.
