My 2 Year Old Son Swollowed A 5c Coin 6

My 2 year old son swollowed a 5c coin 6 days ago. He chocked but quickly ingested it. I have not seen it pass in a stool, but today he has had horroble smelly loose bowel motions that are burning his bottom and it looks like it may have blood in it. He said hos tummy is sore.
