Hi Linda,
My spondy does involve a bilateral pars fracture. I'm 43yo, and to this day...I still have no idea how this happened to my back. The doctors I have seen cannot say for sure if I was born this way, or if it happened due to some traumatic fall I had as a child. What I do know, is that I've had it for as long as I can remeraber which is probably back to my early 20's. The reason I can remeraber having it, wasn't so much due to the pain...but rather a physical deformity at my L5. I have a boney protrusion, which I've been told is the spiney process of my L5 vertebra. It literally sticks out (almost like a tail) and is especially noticeable when I bend forward. It freaks a lot of people out when they see it for the first time. Like you, my pain is worse first thing in the morning when I wake up. But I also have severe DDD at that level, too...so I'm not exactly sure as to what is causing the pain. Before I even attempt to stand up and walk, I have to do a 20-minute stretching routine while I'm still in bed...just to loosen up my stiff and tight lower back. Getting up in the middle of the night to go to the bathroom is a real treat! I have to hold onto things like the wall, dresser, door frame, etc...just to make it to the stairs...and then I have the joy of getting down 6 steps to the bathroom. Sometimes, I will actually debate with myself if I really have to "go" bad enough...or if I can hold it until my wake-up time, because it is such a pain (literally) to get out of bed so abruptly.
Anyway...I don't have much in the way of advice to offer you...only my sympathy because I can relate to what you're going through.
