If you have diabetic foot, it is necessary to check the condition of your feet every day. When washing your feet daily, observe the color and shape of the feet, whether there is any skin damage, and whether there are changes in local color.

Secondly, more professionally, you can feel the pulsation of the dorsal artery of the foot to see if it is normal.

Third, insist on washing your feet daily to maintain cleanliness and hygiene. Be careful that the water temperature for soaking should not be too high, preferably not exceeding 40 degrees Celsius, and do not soak for more than 30 minutes.

Additionally, trimming nails is very important. Do not tear them with your hands to avoid damaging the skin of your feet; use scissors to cut long nails.

Another important aspect is shoe wearing. It is best to wear loose-fitting shoes to avoid rubbing against the feet and breaking the skin.

How to relieve pain in diabetic foot?

If diabetic foot is combined with pain, it often depends on the severity of the diabetic foot. It has a Wagner grading system. If there is an obvious wound that extends to the bone, anti-infection treatment is very important, and surgical assessment is necessary to determine if the foot can be saved. If the wound is superficial and only involves the epidermis, local anti-infection and circulation improvement are fundamental. In such cases, COX-2 inhibitors and non-steroidal analgesic drugs may be used. If the pain is caused by peripheral neuropathy, the first step is to nourish the nerves, for example with mecobalamin, and treat the neuropathy with drugs like epalrestat, along with drugs like cilostazol that improve microcirculation. Effective treatments targeted at this type of neuropathic pain include drugs like pregabalin and etoricoxib, designed for bone pain, and gabapentin-related medications can also be used. (Medication should be used under the guidance of a doctor.)

The precursor of diabetic foot

Diabetic foot is commonly seen in patients who have had diabetes for over ten years, often due to poor blood sugar control and inadequate care. There are three factors that lead to diabetic foot. The first is vascular factors, often accompanied by arterial stenosis in both lower limbs, leading to blood supply disorders. The second is neuropathy, accompanied by peripheral neuropathy, insensitivity to temperature and pain, which makes it easy to suffer burns and external injuries to the foot. The third factor is the presence of an infectious trigger. When these three factors combine, the risk of diabetic foot becomes very high.

Can diabetic foot be cured?

Diabetes has many complications, and once detected, the complications of diabetes cannot be completely cured. Diabetic foot is a relatively serious complication of diabetes. Diabetic foot generally involves many years of underlying vascular and nerve damage that eventually leads to infection or ulceration, resulting in the final formation of diabetic foot. Whether such a serious complication can be cured actually depends on the duration of the patient’s condition, the extent of the lesion, and most importantly, how soon they seek medical attention. For instance, if the infection is very severe, has damaged the bone, or if there is dry gangrene with local tissue necrosis in the foot, then no matter what conservative treatment is applied, it will not be effective, and surgical amputation will be the only option, meaning the foot cannot be saved. However, if some individuals only have early-stage skin ulceration that cannot heal, or if there is an infection that is not very severe, and they seek medical attention early, controlling the infection and treating with nerve nutrition and vascular protection can actually heal the ulcerated area of the foot.

Symptoms of diabetic foot

The symptoms of diabetic foot can be categorized into those without wounds, commonly referred to as stage 0 diabetic foot. The main symptoms of stage 0 diabetic foot include lower limb paralysis, pain, intermittent claudication, severe lancinating pain, and other sensory abnormalities. This is what constitutes a stage 0 diabetic foot. Stages 1 to 5 of diabetic foot progressively involve wound ulceration, typically presenting as progressive ulceration, pain, and exudation. Therefore, it is recommended for diabetic foot patients to seek timely treatment from an endocrinology specialist, and to use medications under the guidance of a doctor to avoid worsening of diabetic foot infections and to prevent severe consequences.

Where does diabetic foot hurt?

Diabetic foot refers to those with a history of diabetes who subsequently develop skin ulceration and pus formation on the feet, which can progress to localized gangrene or gangrene of the entire foot. This condition is then termed as diabetic foot. It is usually due to three factors: The first is vascular factors, often accompanied by arterial narrowing in both lower limbs, leading to ischemia and hypoxia. The second is neurological factors, typically accompanied by peripheral neuropathy, causing numbness in both feet and insensitivity to pain, thus often pain is not felt. The third factor involves the presence of an infection. These three factors together make it easy for diabetic foot to develop. Therefore, most patients with diabetic foot do not feel pain. However, if the neuropathy is relatively mild or is a painful neuropathy, these patients may feel pain in their feet or at the site of skin ulceration.
