I really appreciate your response. As you can see I'm still here, still have the same exact head pressure, virtually 24/7. Eight straight years of it, and it's caused a lot of problems--concentration and learning are affected badly.
There's a strong likelihood the problem is caused by stress, as I'm a very anxious person and the problem began when I went through a very stressful period, several panic attacks during that time as well.
But as far as stress relief, I don't really know. Taking a 4 mile walk helps me feel better, but it's tough to tell if it relieves the head pressure. It's become clear I don't really know how to handle this myself, because of a discipline problem: for instance, if there's a strong chance something will not work, then I won't usually go through the effort of trying it. I'm much more of a "quick fix" person.
I've thought about chiropractors, but a lot of folks say you should avoid them. I'm now interested in trying Flexeril to see if muscle tension is a contributing factor, but my psychiatrist never calls me back, even after telling me "research it and then call if you're interested." In other words, I don't know what to do.
