Substrate is very often a big debate in keeping tortoises.

There are four major types of headache: vascular, muscle contraction (tension), traction, and inflammatory. The most common type of vascular headache is a migraine. Migraine headaches are usually characterized by severe pain on one or both sides of the head, nasuea, and, at times, disturbed vision. Women are more likely than men to have migraine headaches.
Response from Orly Avitzur, MD, MBA. The 2nd edition of the International Headache Society (IHS) classification recognizes NDPH as a separate entity from chronic tension-type headache -- it is described as unique in that the headache is daily and unremitting from the moment of onset and occurs typically in individuals without a history of headache.
