I suffered an upper left abdominal injury playing basketball it been a couple of weeks and while it is improving I still am not 100%.  I think It is improving.  I suffer none of the symptoms of spleen injury except I have a little pain and when I take a deep breath a little tightness.  Question does this sound like a spleen injury?
Hither are many grades of splenic injury. Minor injuries to the spleen doesn't need surgery. As the trauma occurred couple of weeks ago, nothing serious. There might be pain due to musculoskeletal cause. It will be relieved by Skeletal muscle relaxant tablet. If you want to confirm, you can get an Ultrasound abdomen. Nothing to worry. Wish you good health. Regards
