As an accident prone "athlete" I'm a big fan of Cleveland Clinic's sports health facility. They offer same day appointments for sports injuries, which is good when you know you're seriously injured and don't want to have to deal with the hassle of going to the ER or urgent care. Why wait multiple days when you can get an on the spot diagnosis and treatment plan? There are a variety of doctors on hand any given day of the week to treat whatever body party you may have injured. They also have on-site x-rays and MRIs to help expedite the diagnosis/treatment process.
Depending on when you're there, you might just see one of Cleveland's athletes waiting for treatment, too!
