I Fell Down A Flight Of Stairs A Little Over

I fell down a flight of stairs a little over 2 weeks ago. I was carrying a drawer and fell on the drawer and broke it. I went to the ER. Was x-rayed and all was well except for some bruises. In the last few days, I've been noticing a pain/tenderness
on my left side of my navel (upper, at about 1:00, if you were facing me). it hurts randomly with pressure from waistband or if I press on it. Could this be a missed tear of some kind?
