Other medical conditions that can create ringing in your ears include: 1  age-related hearing loss. 2  muscle spasms in your middle ear. 3  Meniereâs disease (an inner ear condition that affects hearing and balance). 4  temperomandibular joint disorders that cause chronic pain in your jaw and head.
Hearing changes. Some chemotherapy drugs for lung cancer cause ringing in the ears (tinnitus). You may also find that you can't hear some high pitched sounds. Some people also feel dizzy and lose their sense of balance. Let your doctor or nurse know if you have any change in your hearing or if you feel dizzy.
