Hi,
My mom (67 years old) has been taking Cymbalta for her Fibromyalgia for almost 4 months. The Cymbalta seems to do a great job with her pain. However, in the last month ot so she's been suffering from horrible headaches and nothing she takes for the headache pain helps. I was wondering if it is possible that this type of side effect can start 3 months after she's been taking Cymbalta.
thanks!
