For as long as I can remember my right, top part of my rib cage has had a giant bump on it that others can obviously notice. When I run, walk fast, or exercise, it hurts and aches right there. Last year after excercise it would swell and be awfully tender until one day had passed. This year it continues to occasionally do it. Right now I have the flu and it is swollen and aches when I cough. This year as well something scary happened where I was sitting watching a game and the whole right ribcage felt like something was traveling up it and stabbing me. It was scary and one of the worst pains I have ever felt. Please give me an idea if you know what this is or if you have ever seen a patient with this.
