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.
When someone complains of ringing, buzzing, or clicking in their ears it is called tinnitus. Ringing in your ears has many causes. If you've just attended a concert and you're wondering why your ears are ringing, you'll be happy to know that the ringing will likely go away in a day or two.
