My partner fell down the stairs on Saturday, he took Difene 75mg for severe rib pain, he did not pass a bowel movment for 3 days went to the doctor yesterday, she prescribed Dufolac, he has now some relief, but feels cramps when he eats or drinks, his rib is not broken, his bowel is now giving him more trouble, could this be related to the fall or the Difene?. He is not taking them any more
