@johnwes5819 If you've had chem profile (which looks like liver enzymes, kidney function, lipids , electrolytes, LDL -. which is elevated with injury in body tissues, especially the heart, liver, kidney, muscles, brain, blood cells, and lungs, etc) and a CBC (complete blood count) and, i hope, a C-reactive protein test and ANA (for autoimmune diseases) all were in normal parameters, this is reassuring. AND if they've been repeated and are still reassuring, doubly so. Now these tests are not diagnostic but they certain often provide clues if something is potentially seriously wrong and/or progressing. If all seems pretty normal, I don't buy the current wastebasket diagnosis that many physicians turn to - oh, it's anxiety , it's depression. no, sometimes it is sloppy investigation and not keeping up with research on drug side effects and reactions and not thinking outside the proverbial box (because the "regular" box is easiest and I know docs are stressed and pressed for time). But don't give up. If I were you, I'd want a neurological exam (things like MS can sometimes present in unusual ways), a consult with an endocrinologist and a consult with someone who specializes in dysautonomia. There is also a chance you are being exposed to something in your environment - a chemical or pesticide.. something to consider, especially if your symptoms change when you are on a trip or away from your home for a while.
