Migraine Headaches Support Group
Migraine is a neurological disease, of which the most common symptom is an intense and disabling episodic headache. Migraine headaches are usually characterized by severe pain on one or both sides of the head and are often accompanied by photophobia (hypersensitivity to light), phonophobia (hypersensitivity to sound) and nausea.
I don't know what might be happening with you. Could just be a more intense migraine. But it's always advisable to speak to your doctor if you feel concerned.
I hope you feel better soon.
