A thorough study to ascertain your pulmonary functions, a spiral CT scan to determine the absence of air pockets and possibly a pulmonary stress test in a recompression chamber should help your physician determine if you can dive again. My Meniere's disease has been stable and I've experienced no dizziness for 10 years. I would like to try scuba. Meniere's disease is a problem of the inner ear with no known cause. The dizziness is a spinning or whirling feeling and may cause problems with balance.
Some people feel nauseated and vomit during an attack.
Some people also notice some hearing loss, especially with sounds that have a low tone. These symptoms can easily be confused with an inner ear decompression accident. Since you have been attack-free for 10 years, it would appear that you are under no increased risk for vertigo under water. However, there is no guarantee that the effects of pressure won't cause an attack of Meniere's.
