As per your history, you are suffering from sudden sensorineural hearing loss, which recovers up to two months only from date of onset. It is not related to non-functioning pituitary adenoma. You can dive or swim. It is not directly related to hearing loss. Rarely after deep dive and sudden ascent, causing decompression, round window rupture may occur causing sudden hearing loss. It is always soon after dive and not later and also after deep diving.
