Hi, Welcome to HCM. Based on the details mentioned in your query I am also suspecting infected abscesses which could be due to secondary bacterial infection of an allergic reaction you had to the insect bite. For now, I suggest you get the pus drained from those swellings on the chest and get a culture done for that pus sample. Drainage of the pus will lead to faster healing of the wounds and the foul smell will reduce. Proper cleaning and dressing of those wounds will also reduce the foul smell and cause faster healing. If augmentin does not show any reduction in infection after 5 days, repeat culture is recommended. I am also suspecting that you are very anxious about these wounds which is increasing your stress levels. I suggest you relax and take appropriate steps to get those wounds dressed and treated. You will definitely see improvement within a week. Wishing you a fast recovery. thanks.
