It is possible!
Hi and thank you so much for this query.Anxiety
can cause these symptoms. How long they last depends on how often you get anxiety episodes. If you are in a constant state of anxiety, then your symptoms would go on as long as you are in this state. this can take days and even longer.
This diagnosis of anxiety could as well be revised. Looking at your history and how any questions you have asked, you see not convinced that you are in good health even after all the detailed and several tests have suggested that you have no detectable abnormality. A concerned you are moving closer to a hypochondriac and this in itself would worsen your anxiety state and aggravate these symptoms.
In all, yes anxiety can cause these symptoms. You need to believe in what your doctors and the various investigations conclude as concerns your health status.Being worried with no justified reasons only worsens the clinical state and aggravates symptoms.
