The blisters on the feet of diabetic patients are generally seen in patients with a long history of diabetes and poor blood sugar control, often combined with peripheral neuropathy of the lower limbs, clinically known as diabetic maculopathy. If a diabetic patient has blisters on his feet, he must go to a regular hospital for treatment, first of all, to control his blood sugar well, use a sterile needle to draw out the contents of the blisters, strict local disinfection bandages, and regular drug changes. If you find that the local skin of the blister has broken down, in addition to changing the medication, taking drugs that promote wound healing will also facilitate the absorption of the blister and the healing of the wound.
