[|Human|] I get this shooting like nerve pain in the left side of the back of my head, Not horrible, annoying. Same spot. Sometimes if I have a little heartburn the shooting sensation will appear. Same spot, no worse. I thoght it may be tooth related since I did have a root canal done of the left side. I have been back to my dentist and he doesn t see anything.
[|AI|]  Hello! I read your question and understand your concern. In my opinion the shooting pain in the back of your head is very suggestive for occipital neuralgia. I don't think it is related to your tooth as there is no anatomical relationship between the two structures. Teeth may cause trigeminal neuralgia, which is in a different location. Occipital neuralgia may be caused by the compression of the nerve in the upper cervical region. Generative cervical spine disease may cause it or maybe also the standing position of your head in the dentists chair. I recommend you to take indomethacine twice daily for 10 days of course if no stomach problems. It is very effective in this type of headache. If the problem persists I would recommend you to consult with a neurologist and have further tests. Hope to have been helpful. Best wishes
