Hello, I fell last Friday morning, hitting my head on a concrete block, went to ER for stitches.. Later that evening I was sore which was naturally expected. Long story short my right chest area and beneath my right arm on that side also is painful....chest area hurts worse when I lean over for any reason. Today it is very painful...no coughing, no pain on coughing etc but wondering if this will just take time to heal or with it being a week now, should I go to my doctor?  Thanks
