It really depends on your symptoms and functional status.  If you have had no change in these it may not be necessary to have yearly stress tests but you should discuss this with your physician.  Also if you are able to walk on a treadmill you can avoid the medications that are given in pharmacologic stress tests that are likely causing your headaches.
