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.
Learn what causes that ringing in your ears, and how you can control it. Cymbalta which is usually prescribed for major depressive disorder or MDD, comes with a wide range of possible negative side-effects, including tinnitus.
