One common cause of hyperprolactinemia is a growth or tumor on the pituitary gland called a prolactinoma. The tumor produces high levels of prolactin. These tumors can be large or small and are usually benign, meaning they are not cancerous. Large tumors can also cause headaches, vision problems, or both.
The most common symptoms of atypical antidepressant withdrawal, including Cymbalta, are anxiety and low mood, such as apathy and rebound depression. Because Cymbalta strongly affects serotonin, after discontinuation it can take several days for the body's own serotonin system to return to normal.
Cymbalta 30mg up to 60mg has not helped me with my depression or fibromyalgia pain. I consistently feel like I'm drunk with low energy. While coming off of the medicine I experienced severe headaches, confusion, unstable gait and still felt drunk. I can sleep 18-20 hours a day and have vivid nightmares.
