I disagree with this one... although a particular symptom may not interfere with daily functioning, it is important that your therapist and doctor know all the symptoms you are having. Being a symptom means something is causing that. Like someone else on here said, when they have these symptoms, it makes them realize they are too stressed and take appropriate actions to ground themselves. Revealing such a symptom could help the client and therapist discuss what the root issue is, and therefore create a better treatment plan.
