Did I experience a migraine or something else?

Migraine can be triggered by stress, so it definitely seems like it could have been one. I have had migraines and I lose my vision when I have them, where I get blind spots which last for half an hour. It is highly likely you will have another migraine in the future, so if you experience blind spots, tingling in the body, vomiting, these are normal symptoms relating to migraine however if you experience slurred speech, mouth droops, and muscle weakness in your arms and legs you should call an ambulance because it may be a stroke. Migraines are harmless but it is important to know the difference between the symptoms of a migraine and a stroke. I hope this helps, take care x
