A week ago my aunt develop a lesion on her shin. She told that it was like a pimple. It was not painful but was tenderness on pressing. It was itchy also. She applied boroline to it. Later when she showed me this, I took advice from nearby doctor and applied betadine ointment, T bact and tab.azee. She is pre-diabetic (
HbA1C-6.1). What else care should I take to heal up the wound?
