In 1998 I suffered a Pica stroke and was very fortunate as other than a little balance disorder I was left with no risidual problems. I also had TIA six months before my stroke. Now I have developed a toothache, a little headache on occasion and chirping in my right ear only. I just had a MRI which show my old injury as well a s a mild degree of periventricular small vessel white matter ischemic disease and a incidental right maxillary retention cyst which is small in size. Food also does not taste right, however it has not stopped me from eating. I have chirping in my right ear which sounds like little birds. I am going to see an ENT specialist and do not know what is going one. Any ideas???
