I had atlas profilax done about 6 months ago, due to chronic pains over the last decade, including years of chiropractic promises to "keep my atlas in" to no avail. I chose Atlas Profilax because it indicated "permanent placement" of the atlas. Afterwards, I experienced 3 or 4 days of sheer bliss, which I knew had to do with endorphins, and I was prepared for a resurgence of symptoms, and knew I had to be patient. Boy, have I had a resurgence. TMJ was one of my problems that I was hoping Atlas Profilax would help. It didn't - only got gradually worse. SO I find a TMJ specialist whose credentials include dentistry, but upper cervical as well, among many other things tied into TMJ. (This is orofacial jaw pain for those who don't know). So I go to this specialist. He appears honest, and he has no motivation really for lying to me, especially about my atlas.... and he tells me my atlas is indeed out. (I have very misaligned bite as well, which he thinks is the core of the TMJ). Anyway, this was 5 months after my atlas profilax treatment. I thought it was permanent 99.99% of the time, and yet I'm informed that my atlas is out. (It felt like it was out for months, but I just kept telling myself this was part of that "resurgence of symptoms".) Hmm. But I probably was right that first time I suspected it was out, about a month after I had it done. Don't know what to think now. Has anybody else had this experience??? Please write, I need to know more.
