Even though you may think your doctor knows best, you must always remember to be your own health advocate. Oftentimes, doctors are over-scheduled and they might miss a diagnosis that's been causing you to feel out of sorts.

It may be hard, but before seeing your doctor you should make a list of symptoms you're feeling, how often you've been feeling that way, and if you've made any recent changes within your health's history. Even though your doctor might ask you questions and request certain tests, it can be extremely frustrating when nothing is being diagnosed; so it's important that you take measures to be as prepared as possible.

You know your body better than anyone, and it's crucial you always listen to it when you're feeling out of sync.

What should you do if your doctor has run numerous tests but you're still undiagnosed?
