My partner was assaulted and we thought he had a broken rib, but it wasn't getting better. Then he lent over,felt sick, and pulled up his t-shirt ski could feel his heart racing. I watched his chest as a lump formed in his pec muscle and moved to his sternum, then travelled down his sternum to rest at the base of his sternum. He clutched his belly cuz it hurt and he wanted to stop it going further. Called 999 and Wen they got there they had no idea as he was no longer in pain. So they left but the lump is still there and it's slightly bruised. What is it, does he need to see a doc? Wen e went a&e about his ribs the x-ray found nothing.
