Please help. i need your advice
Hi short answer could be a gangrene Detailed answer Thanks for your question to this forum. Based on the information given by you in this question it seems that you have developed peripheral vascular disease and peripheral neuropathy of the toe. Patients with long-standing diabetes are also prone to various types of infection including fungal infection. The physical examination by an expert to conclude the final diagnosis is recommended. Do not scratch but take some antihistamine tablet to prevent itching. Because after scratching and bleeding you are more prone to infection. Thank you
