Can i have bruised my spleen?

Yes, with trauma: Trauma to the left upper portion of your abdomen or the lower portion of your left ribcage can result in a splenic injury, either a laceration or bruise/hematoma of the spleen. The main worry with a splenic injury is bleeding. A hemodynamically stable patient with such an injury may be put at bedrest and followed closely. Others go to the OR for repair or removal of the spleen.
