My boyfriend jumped from 30 feet up into a lake today. Immediately, he felt pain and as though water got into his ear but he could not get it out. One hour later, he had intense vertigo and the pain continued. Now, 7 hours later, he still has pain, dizziness and vertigo to the point where he vomits when he stands up. We are on vacation in Mexico, and therefore don't have insurance to get it checked out.

Is this a burst ear drum? How long will vertigo last?
