Colleen, you bring up a good point. Not all symptoms are attributable to an AN. So, we need to be careful to differentiate.
In my case, just before Christmas I was feeling dizzy on our last day at work had to bend over and nap on my desk. I was thinking, and probably those around me, that my AN was getting worse. Next day I discovered I had a an infection and a course of antibiotics fixed me up.
Soon after I got a headache, and again thought my AN was getting worse. Then I realized that I got work late that day and skipped my cup of coffee. Culprit found.
ANs do have several possible symptoms, but a doctor should be able to differentiate between AN related symptoms and non-AN related symptoms. If you're on wait and watch for several years you will undoubtedly get a problem with symptoms that can be associated with an AN. It's important to get them checked out.
In the case of the tooth, the giveaway was that it hurt when drinking cold liquids. This means it is a dental problem and not referred pain from the AN.
In summary, not all (new) symptom are due to an AN or not due to an AN. The new symptoms needs to be checked out.
