It is important to know the signs and symptoms of diabetic foot, as serious complications can arise if the foot is left untreated. Catching the condition early on can also provide a better opportunity for successful treatment and slowing down the progression of the condition. Symptoms of diabetic foot are often worse at night, and can include numbness in the foot, reduction in the ability to feel hot, cold or pain, burning or tingling sensation, sharp pains, increased sensitivity to physical contact, additional foot problems such as infections, ulcers, and pain in the bones and joints, as well as unusual or persistent foot odor. If you have diabetes, a doctor familiar with diabetic foot can let you know what symptoms to watch out for and how you can reduce your risk of developing diabetic foot.
