Hello, For Over A Month Ive Been Experiencing Frequent Heartburn

Hello,
For over a month Ive been experiencing frequent heartburn and pain in my upper right abdomen close to my rib cage. After a trip to the ER, it was determined that I had strained a muscle in my chest wall and was sent home with instructions to take my pain meds and muscle relaxers for the next four days and that should be it. 2 weeks later I am still experiencing pain and heart burn as well as slightly yellowish eyes. wondering if I should just wait and see a doctor or go ahead to the emergency center?
