Difference between: throbbing, pounding, splitting, stabbing, and blinding headache? i have an idea but how in simple terms would you describe each?

None: There really is not much difference between these terms as they all indicate a very severe headache. Doctors would characterize the headache further by asking were the pain was ( whole head , one side or another etc..) things that provoke and relieve it, and if there are other symptoms associated with it, like weakness in an arm or leg, nausea, difficulty speaking, visual problems etc..
