Ok how can i tell differ n a cluster headache from a sinus headache ? i put a hot rag on my eye and it ease up. my pain is right above my left eye.

You can, very easy: Cluster headache is the most painful of all the primary headache disorders. Because of the intense pain, cluster patients often pace the floor or bang their heads during headache episodes while rubbing or holding the painful site in any attempt to distract themselves from the pain. Some patients say that "my eyeball is being pushed out," or "there is a hot poker sticking in my eye". That's it.
