What causes left-sided headache and burning sensation in head, sinus and nostril?
I read your question carefully and I understand your concern.
Judging by that description I would agree with your doctor in saying that the most likely diagnosis is sinusitis.
However since it doesn't seem to respond to be promptly responding to therapy some confirmation through imaging is advisable. For that purpose the CT scan would serve both to confirm sinus infection as well as to exclude other possible causes like a tumor.
You mention TIA which would raise the question of a possible stroke, but I do not think it is the case as the location of the pain is not typical and usually there are other symptoms (like weakness of the limbs on the contralateral side).
One other possibility to be considered is also a condition called temporal (or giant cell) arteritis, inflammation of the arteries, mainly temporal artery which can manifest with unilateral headache. For that your physician should keep in mind palpation of the temporal artery during physical exam as well as a blood test for inflammation changes like raised erithrocyte sedimentation rate.
I remain at your disposal for other questions.
I hope you will feel better soon.
That blood test shows a mildly raised white blood cells count. It can be a sign of infection, but is not specific, meaning does not indicate the site. Could be justified by sinusitis.
As for the erythrocyte sedimentation rate which I mentioned before it is not included in these results. A moderate increase of it though may occur also in the case of infection, so one must think of temporal arteritis only when values are really high and are supported symptoms and physical exam.
The ECG shows a previous anterior infarct....perhpas it's an already known fact and it has no relation to your current symptoms. I suppose the doctor addressed that, but in case not it warrants some attention regarding risk factors, heart function and future preventive treatment.
I hope to have been of help.
I greatly appreciate your help.
As I said that has no relation with the headache and wouldn't want you to worry too much about it, since it was noted years ago it does not represent an emergency.
But once the headache issue is resolved, if you have not been evaluated and take no treatment for your heart and blood thinners, a check up with a cardiologist is advisable given that old MI and the chest pain episodes.
Wishing you good health
