Hi Sue, The ringing in the ears is called Tinnitus. It can be a side effect of medications (check what you are taking) or for me, it can also be a sign that a migraine is on the way. It could also mean a number of many other things, depending on other symptoms you may have.
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. 5  head and neck injuries.
