Welcome to Chat Doctor, I want you to be physically examined by a physician before giving medications to you.  Do you have chest pain?  Do you have sweating?  Pain below the left arm may be due to enlarged lymph nodes or lymphadenopathy in that area do you feel any lumps in the breast on self-examination?  Is your breathing problem is associated with cough?  If so is it productive or a simple Chat Doctor.
