Well mainly because it is such a long process. And to them, not trying to sound like a jerk but, if it was that bad why did you wait so along. At first they thought i was faking, then they seen how i was and realized i wasnt faking it. That's what they did to me. Im in the army. And they go through a long huge gamut of treatment. And can take up to a year depending on severity. They will try group therapy, one one ones, acupuncture, and of course meds(ive been through over 5 kinds), they will send you to all sorts of other classes, may do a sleep study or two, and have you try a different diet. They also tried hospitalizing me but i couldnt take being away from my family. They had me do the essential oil machine thing. All sorts of stuff, natural and medecine. I believe this was all they tried for me. Which I also have back problems, my back dr said he's putting in request for meb and advised I should go back for ebh. So i went back then he put in a request as well. Did a follow up with pcm and she started it cause I had two notes from two different drs saying I should get meb. I was going for close to a year may be a little more, got better for about a month then it slammed me again. Went back. Now im waiting for my ratings and my no later than date. Hope this helps. Hang in there. It can and will get better. Keep fighting the good fight. Oh and always, I repeat always let them know how it negatively affects your work amd personal life. They want to hear that.
