My migraines from years ago always had aura, ten headache and full on migraine lasted six weeks.
This one however was different: pain all down the lft side of head and bad nausea, although not vomiting and no aura.
My GP said it was a migraine and put me back on Parramax, a combination of paracetamol for the headache and metclopromide for the nausea. It worked.
