When my blood sugar drops to just about or a bit below 70 mg/dl, I will usually get a pulsing headache behind my left eye (always the left) that does not respond well to headache medication and does not usually retreat, at least not completely, despite bringing my blood sugar up to the normal range. It takes hours and multiple dosings of OTC headache medication to do the trick. Sometimes it will linger until I fall asleep that night.
I also suffer from cluster headaches, albeit rarely. However, a hypoglycemia headache can trigger a cluster headache for me, which happened last weekend. Even when they do not trigger a cluster headache, they can be debilitating in their pain intensity.
Does anyone else experience this or have recommendations on how to handle these headaches? I recently got a CGMS so that should help me avoid them to some degree.
