They both start in the head. Different parts of the head. They both send pain via the trigeminal nerve but that's where the similarity ends. The biggest connection between M and CH is that Dr's don't know squat about CH so they call it meegraine. Here's an little comment from Doc Goadsby's Hypothalamus Article (you can find the entire article in the OUCH Research Library): "In contrast to migraine,25 no brain stem activation was found during the acute attack compared with the resting state. This finding is remarkable because migraine and cluster headache are often discussed as associated disorders and similar compounds, such as ergotamine and sumatriptan, are used in the acute treatment of both types of headache. These data suggest that while primary headaches, such as migraine and cluster headache, may share a common pain pathway (the trigeminovascular innervation), the underlying pathogenesis differs substantially as might be inferred from the different patterns of presentation and responses to preventive agents.26 "
