What Causes Feeling Of Electrical Impulses Above The Left Ear?
Read below.
Detailed Answer:
I read your question carefully and I understand your concern.
Reading at your other previous and current diagnoses though I do not think there is any association between any of those issue and this current complaint, none of those conditions do manifest or complicate with that symptom.
As for what could it be, one possibility could be occipital neuralgia, irritation of the occipital nerve which supplies that area. That irritation could be due to compression in the upper levels of the neck where it exits the spine, commonly due to arthritic changes.
One other possibilty could also be mastoiditis, an infection of the mastoid bone air cells behind the ear, commonly associated with ear infections.
I remain at your disposal for other questions.
