With the improvement of the standard of living, the incidence of diabetes is getting higher and higher, and it’s fine if the blood sugar is simply high, but its complications spread across all systems of the body, and the heart, brain and limb vascular disease it causes can be disabling and fatal, which many people know. The trouble is that it causes itchy and dry skin, painful feeling in the limbs, feeling that the limbs have nowhere to put, coldness in the hands and feet, unstable walking and soft feeling in the feet, easily broken skin that does not heal easily, sweating and coldness, general weakness, poor night rest, and many other unspoken or unspeakable discomforts that do not attract the attention of diabetics or diabetics-to-be. If the above-mentioned manifestations occur, the diabetic killer may have already entered your peripheral nerves, so pay attention! It’s never too late to prevent it.
