One such patient, thinking his son was a doctor, wanted our specialist to mail him the medication for his treatment and then have his son change his medication at home. It’s not that I didn’t want to mail them, but I was afraid that it would delay his condition and be bad for him instead. In fact, in our hospital, if the early symptoms are effectively controlled, and the later stage is recovered to a certain extent without any major problems, we will agree to bring the medication back to the patient, so that the family can just change the medication for the patient according to the doctor’s instructions. Why not from the beginning? Because we do not know the patient’s situation, early infections, metabolic disorders and other health conditions. For example, the external application of our Chinese ointment requires effective debridement of the infected necrotic inflammatory tissue before it can be done, without debridement, this layer of inflammatory tissue will prevent the normal tissue from absorbing and transporting the drug, and the drug effect will not be effective. Some people may say, can’t you clear the wound yourself? If you know the tissue structure, can distinguish tendons, muscles and blood vessels, can identify normal tissue and necrotic tissue, and have a good grasp of tissue removal, it is also possible, but the problem is that only a professional doctor can do a good job. For example, in our hospital, there are several kinds of Chinese ointments, oils and potions, as well as different adulterants and dispersants, which together can be used in many ways. However, it is difficult to take into account all aspects of care at home (even in general outpatient clinics and inpatient wards), for example, in addition to conventional therapeutic care, there are also dietary care, psychological care, rehabilitation exercises, etc., all of which need to be done by dedicated personnel, can they be done well at home? All in all, the treatment of diabetic foot is a comprehensive and holistic treatment, involving many issues, and it is not a job that any doctor can do. I hope that you will have a comprehensive understanding of diabetic foot and never take it for granted, leading to more and more severe wounds on your feet and causing avoidable damage to the patient.
