Welcome to the Migraine and Headaches Forum! This forum is for questions and support regarding migraine and headache issues such as: abdominal
migraines, headaches caused by allergies, cluster headaches,
headaches, headaches in children, migraine headaches, sinus headaches, tension headaches, visual disturbances.
Migraine are generally preceded by an aura, but sometimes there is only aura not followed by a headache, or only headache not preceded by aura. The severity and one sidedness of the pain suggests it is most likely a migraine attack. I would suggest you to lie in a quiet room and apply cold compress to the neck. Also as rightly mentioned magnesium is known to benefit patients with migraine.If possible try and identify the trigger for your migraine.
Just to add to the information, what you have is the "common migraine", which is not associated with an aura. It is the "classic migraine" which has aura with headache.
