What Causes Pain In Ribs Below The Breast Bone On The Right Side?

Hello,I am Okediji, Victor Mishael by name. I will like to make a complain about untraceable pains I use to experience by the right hand side of my ribs below the breast bone,right on one of the costal cartilage,within the right atrium arena,against the tommy wall, and it also use to extend to the back below my scapula. The pain always occur within my skin layer,and I use to feel it like when someone is having burns.The skin around this spot sometimes swell up, and i treated it before i left my home country to study in America. When I came to USA, I went to my School Health center, they did some test and X-ray. but they couldn t trace anything. but, I am not comfortable with it because the pain is still occurring. Secondly, I don t really understand the nature of my penis.Early in the morning or at night it will look appreciable. but, when ever i am taking my bath or shower, it will become shrink, and at time it won t. It use to be very small and time when ever it shrinks. I will like you to give me possible solution to my health problem.I am a martial arts athlete, and my health status is really discouraging me. In conclusion,I have my health issureance certificate as an international student.
