<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hi doctor, I have been experiencing sharp chest pain for the past week. I also have a wound on my chest that wont seem to heal. I must tell you that I have had a history of drug abuse.  <response>: Based on your symptoms, you seem to have an open wound of the chest. The sharp pain you feel could be due to the exposure of the wound. I would advise you to stop using drugs immediately and come in for treatment as soon as possible to avoid further complications.
