I decided to go to the doctor first when I found a small painful lump near the nipple. Subsequent blood tests revealed a high level of prolactin, 5700 the normal amount being 40-400. The size of the tumor was 9 mm. thereafter, I began to take Dostinex. The tumor shrunk by half its size. But I experience the following side effects such as headaches, giddy feeling in the mornings, immovable joints and dizziness. My behavior has changed in that I have become an outgoing person. I have begun putting pressure on relationships. I now get extremely high levels of libido now. I am feeling very young now.
