Hello and welcome, Thanks for your query. Let me try to put forward another possibility if this helps. You are a post-menopausal woman, and Migraines are common in this age-group, although seen in other age groups as well. The symptoms are: -Photo-sensitivity -Irritation to noise -An aura like presentation before the migraine attack which includes a mild headache and even at times black spots in vision -Nausea and even vomiting -Neck stiffness Please note, not all symptoms need to be present during a migraine attack. Also noted in many migraine sufferers, is usually a triggering factor is present. Most common ones: -Stress -Irregular eating habits (prolonged starvation or excessive eating) -Temperature, etc. If you feel this could be a possibility, kindly consult your doctor or schedule an appointment with a neurologist, as there are many different types of headaches. Also, a visit to the ophthalmologist can also help, to rule out any trouble with vision. I hope I contributed, you could write back to us anytime for further clarifications. Best wishes.
