Tinnitus is the term for ringing or buzzing in the ears.
Most people will have it occasionally or intermittently. It
is often noted after exposure to loud or prolonged noise.
Consuming caffeine, salt, chocolate and alcohol can make it
worse. If it is constant, occurring in only one ear,
associated with hearing loss, associated with dizziness or just
very bothersome, it should be checked by an otolaryngologist (ear,
nose & throat doctor), as it may indicate a more serious
problem.
