A complete clinical examination may be necessary for accurate diagnosis and management. One may feel temporal artery pulsation during periods of stress, anxiety, severe headache, migraines, elevated blood pressure etc. Temporal arteritis also presents with similar symptoms. A physical exam is needed to rule out thickening of the temporal artery .You will need base line documentation and for possible treatable causes. You may need ECG, kidney function, cholesterol etc. A physical examination including the eye fundus is needed. A clinical examination can confirm the diagnosis. Consult your doctor and clarify your doubts. I hope it helps.
Best wishes and regards!
I am 76 and have similar symptoms. I too am taking hctz plus other meds daily for blood pressure, polymyalgia,gout, and suffer from tinnitus. You describe what I feel (MRI shows normal, so did Nuerological tests). Doctor thinks its just a side affect possibly of meds and my hearing problem which exagerates other symptoms. Im 6'0", 175#.
