Physical symptoms are very common in anxiety disorders, sometimes more common than anxiety itself. The hallmark of such physical symptoms is that they cannot be explained on the basis of our medical knowledge (medically unexplained).
anywhere in the body (especially brain) will be associated with a number of other problems related to that particular brain region. Therefore, your apprehension that it might be a tumor (even with a normal CT scan
) is more a part of anxiety problem.
Consult your psychiatrist
and discuss your concerns with him. A minor change in anti anxiety medication
and a lifestyle modification to minimise your stress
levels can help you overcome your problems. All the best.
