Hi thanks for your question.
You are having a nonhealing wound on hand with puss and blister
on it.Your wound is not responding to antibiotics.I would suggest you to consult a general surgeon
who may clean up your wound, may do some debriment and dress your wound properly.He may advise you for the culture sensitivity of the puss from wound.Addationally you may also need to get your blood sugar done to rule out diabetes
as a cause for non healing of your wound.
Hope this answers your question.
