HCM, the pumping function is normal. but the heart muscle is thickened and. stiff, making it difficult for the heart to. relax and for blood to fill the heartâs. chambers. This limited filling prevents. the heart from supplying enough blood. to the body, especially during exercise.
Migraines and cluster headaches are vascular headaches, while tension headaches are not. Cluster headaches are called that because they occur more in clusters and then go away. They usually occur in the exact same spot, and the person often experiences unilateral facial sweating and abnormal facial sensation. Cluster headaches are treated with the same medications that are given for migraine headaches. Tension headaches are not vascular headaches. They don't have that pounding nature. There is more of a constant ache, and often the neck or the sides of the head are involved.
A characteristic of tension headaches is that pain usually occurs on both sides of head and is in the form of a dull, steady ache. Cluster headaches are rare, extremely painful and debilitating headaches that occur in groups or clusters. They often appear during seasonal changes. They are also described as suicide headaches, a reference to the excruciating pain and resulting desperation that has sometimes culminated in actual suicide.
