I woke up early this morning with piercing pains on the right side of my upper chest to the right of my sternum and underneath my rib cage. The pain is worst when lying down and breathing deeply, though has been there all day. I can feel slight vibrations whilst breathing in. Over the last week, I have felt slight pains in the same area but barely noticeable until today. I m not sure if it s linked but my stool has traces of blood in it too, and my visits to the toilet have either had symptoms of diarrhoea, when blood has been sprayed, or being hard and black. Thanks
