Hello does anyone know what this is? initially I was told I had trigemminaneuralgia but today I have been told it is carotiditis, often found in post menopausal women,

when the pain comes deep inside my ear it is transient , severe & like a bonfire !! It stops & starts several times a minute then stops , I can't initiate the pain & never know when it will come back

Thank you to anyone who can shed some light on this
