My boyfriend fell off his bike a week ago. he was really swollen the next day and had difficulty walking. we had him on anti-inflamatory and we iced the area the first 2 days after the accident. about 3 days later a huge dark purple bruise appeared. the bruise has been spreading over the last few days. The bruise is still a deep deep purple and red color and there is still swelling . although less than what there was initially. i want him to see a Dr. he states because he is walking better and the swelling has gone down there is no need. He is still tender in the area. Is there a danger of internal bleeding or damage to the organs? we have watched his urine for signs of kidney damage and none so far. should i be concerned or should i let him ride this out?
