One thing I find is that nagging, minor symptoms that seem to always be present will largely dissipate after I receive imaging test results that put my anxiety at ease. More and more I am coming to realize just how much pain is a subjective phenomenon that is related to, or even dependent on, my attention. For example, after I had a colonoscopy and was given the all clear for colon cancer, the symptoms that were triggering my colon cancer fears more or less disappeared. This doesn't mean they aren't "real" but rather that my anxiety causes me to focus on them in a way that brings them to the foreground and then, because I panic about them, my nervous systems treats them as dire and assigns them a top priority, creating a kind of pain, stress feedback loop.
