Hi,
Welcome to Health Care Magic, Thanks for writing to us,
I am Dr.Ahmad Bilal, I have read your question, I understand your concern and will try to help you in the best possible way.
It's is a rare thing to see carotid calcification in an x-ray until its really evident and severe.
MY OPINION:
Symptoms are usually gradual ,not just a single episode, but with the symptoms you had , in my opinion you should meet a cardiologist , with your record and labs you have had.
What is this:
This may or may not be aortic calcification but you have to get it ruled out before a big event happens.
Your Doctor might want to run some exam and tests on you like ECG, perfusion tests, carotid dopplers etc.
Treatment:
Yes there is a treatment for carotid calcification:
Carotid stenting is widely done and is very efficient then end artectomy is also done surgically. Choise of procedure depends upon factors like choice of doctor, severity and facilities available.
....
I Hope this answers your question, if your have more queries feel free to ask,I will be pleased to alleviate your concerns.Wish you the best of health.
Regards,
Dr.Ahmad Bilal.
