Can status migranous last months ? chronic daily headache with spells where pain ramps up and in severe pain 24/7 untill eventually it breaks . always find it hard to believe can last so long as its normally just my everyday pain increasing?

I'm not quite sure you're experiencing migraine headaches. Muscle contraction tension headaches are a more likely cause of continual headaches like yours. You need diagnostic clarity. I recommend that you consult a neurologist for accurate diagnosis & proper treatment options. Any appropriate testing will be done. You may be referred for stress management therapy depending upon the findings.
