Chronic daily headache and chronic headache are the same beast. When I
started this group some time ago I had to choose Chronic Daily Headache
because many of the other possible names were already in use. Sometimes
these headaches are called a transformed migraine. Many of the things
you listed as triggers for your headaches are also triggers for migraine
headaches. Have the army docs tried any kind of prophylaxis? Many of the
older antidepressants at low dosages can help bring some relief. I've
had daily headaches for roughly 15 years. I didn't get much relief until
I found a pain doc who was willing to aggressively treat me with
narcotic pain killers. The headaches didn't disappear but they are much
more manageable than they were.
You might want to check out news:alt.support.headaches.migraine. Its a
very helpful support group. Just keep in mind that ashm, like many other
support groups has some occasional rabble rousers. Overall, I've found
the group very helpful especially if you are trying to find some
information on headaches.
