Patient's Query

Hi doctor,

My father has an ulcer on his left big toe. A small operation has cleared the area, but some black spots are still inside. Why is this happening? I dress his wound every day.

Hi,

Welcome to icliniq.com.

I am assuming that since you raised a query for diabetology, and considering your description, it is a diabetic foot ulcer. Diabetic foot ulcers are among the most common complications of patients with diabetes mellitus, which is not well controlled, the result of poor glycemic control, underlying neuropathy, peripheral vascular disease, or poor foot care in areas of the foot that encounters repetitive trauma and pressure sensations. Kindly share the diabetic status, diagnostic and monitoring test reports, and prescriptions for the treatments. It appears that the area has undergone ischemia and might have been infected with resistant bacteria such as Staphylococci, and Streptococci, all of which can cause ulcers and black areas, needing debridement and local healing. Treatment requires an inter-specialty approach of diabetologists, surgeons, dermatologists, and podiatrists.

Same symptoms don't mean you have the same problem. Consult a doctor now!
