I was playing intermural football and a guy hit me shoulder first right in my ribs. I though it was cracked then but after I talked to some people I though I only bruised it real bad. Well how I have been in pain for about 10 days and have been taking prescription doses of Ibuprofen (a nurse said it would be ok..I am a big guy) but I am still in pain and it is starting to get sharper. Any advice and is this rib more than likely cracked?
