You’re more likely to have sores and ulcers if you have diabetes. A diabetic foot ulcer is an open sore or wound that usually develops on the bottom of the foot, legs, and other places such as the hands or stomach skin. Anyone with diabetes is at risk of developing a foot ulcer. Insulin users, as well as people with diabetes-related kidney, eye, and heart illness, are more likely to develop a foot ulcer. Obesity, as well as the use of alcohol and tobacco, contribute to the development of foot ulcers. Ulcers develop as a result of a number of conditions, including a loss of feeling in the feet, poor circulation, foot abnormalities, irritation (such as friction or pressure), trauma, and diabetic duration. An increase in blood sugar levels might decrease the body’s resistance to infection and can also lead to delayed wound healing. If diabetic wounds or ulcers are left untreated, they can develop an infection which will lead to gangrene.

Among the symptoms of diabetic wound/ulcer includes:

• Some drainage on your socks.
• Redness and swelling may also be associated with the ulceration and, if it has progressed significantly.
• Odor may be present.

Main symptoms include:

• Blood sugar levels that are too high can harm your nerves and blood vessels. This reduces blood flow (particularly to the hands, feet, and limbs), making it more difficult for sores and injuries to heal. Also, you are more likely to get an infection.
• Nerve damage makes it more difficult to feel pain or other ulcer or infection symptoms. This may prevent you from treating minor wounds.
