Burst eardrums and lungs are certainly a possibility.

Actually, the common problem is that bubbles of air form in the blood vessels. In and of themselves, they are excruciatingly painful - people may become dehibilitated and drown. And they actually block blood vessels, in which case they are known as emboli (singular: embolism) and cause strokes.
