I was your age when I was told I needed to be put on depression medication and that they were "phantom" pains.. If you in general Do not feel good.. then something is wrong.. I would hate for you to endure the 10 years of suffering ,,as I did,, and then come to find out you actually do have something wrong with you.. I Always knew something was wrong and it seemed like I was getting all the generic tests done and no one listened to me,, until I got referred to a Rheumatologist for joint and muscle pain I was having. you should go see one.. they specialize in finding what it is that is wrong with you and cut out all the generic meaningless tests that really show nothing other than a current life threatening illness. Hope you feel better soon and get the care you are needing.
