Hi, I had gone through your question and understand your concerns.
As I can tell from your history I suppose the
aneurysm was an incidental finding, which is not very uncommon, with several reports reporting a 1% incidence. The strategy management of small aneurysms (less than 7 mm) consist on a angio CT per year to see the dimensions of the aneurysm, which in case they stay identical no treatment is recommended.
Regarding the therapy I suppose the doctor saw that you are quite anxious, thus he prescribed the above mentioned ones, which in fact can cause the lighheadness as adverse effect, but the aneurysm is not associated to this, nor to the headache, unless it is a hyperintense hyperacute kind of headache. In that case you should take emergent medical consult.
Basically, I would recommend to change your medication for your
anxiety and assure you the aneurysm you have is not responsable for none of these symptoms.
Hope this answers your question. If you have additional questions or follow up questions then please do not hesitate in writing to us. I will be happy to answer your questions.
Wishing you good health.
