Over 4 years ago I was playing around with my sister when she landed on me, knocking the air out of me for a good couple minutes and sent me into agonizing pain thinking I broke a rib or something. That night I acquired a bruise on my stomach, around my bottom left ribs and where my spleen would be. Now 4 years later, the bruise is still very noticeable and it itches all the time, and even hurts, almost like a throbbing. Does anyone know what this could be or what I should do? Sometimes I will even get horrible cramps directly below the bruise. Do you think it could have affected my spleen but only showed signs of damage now?
