I have intense pain in the back of my head. Is this something dangerous?

Hello,

Welcome to icliniq.com. Your symptoms are not suggestive of any serious medical disorder (including a brain tumor). You should know that a brain tumor usually does not cause an intermittent sharp pain (which is typical of nerve pain), but progressive headaches mainly during the night and in lying down position, with nausea in the morning. Other symptoms, like blurring vision, gait problems, etc., may be present. So, you can understand that it does not seem to be your case. Occipital neuralgia seems to be the most probable cause of your complaints, although you say to have a different type of pain. Coming to this point, I suggest taking Indomethacin twice daily (if there are no contraindications) for some days, coupled with an antacid or PPI (Omeprazole) to protect your stomach. Hope you will find this answer helpful.

Hello,

Welcome back to icliniq.com. No, I do not think it is a brain aneurysm. Aneurysms do not cause such a type of headache. They are usually non symptomatic and may lead to cranial bleeding. Besides, as you have previously performed a brain magnetic resonance imaging (MRI), it is less likely that you suffer from a brain aneurysm. They are usually from birth. New aneurysms during life are usually related to connective tissue disorders or uncontrolled hypertension. So, it is not your case. You should try to relax about this. Does pressure on that point trigger headache? This would be another argument in favor of occipital neuralgia, as the nerve lies on the surface and can be irritated by manual pressure or head movements.
