Hello I have displaced disks I also woke up one morning with clicking..and headaches.. 2 days later I woke up and couldnt open my mouth very wide..couldnt even fit 2 fingers in...as is the case to this day. That happened 8 months ago. I hoped that this would just go away but it never did. I went to 4 doctors/dentist before knowing what I had to do.. It is an absolute you see a tmj specialist! Not just any..but a caring, knowledgeable one. It took me 6 mos to find him. I am now going through the 2 phase therapy to avoid surgery at all cost! its costing me thousands but perhaps your insurance may cover it. I have to put my health before the money, I just want my normal mouth back. Im using a hard lower splint to unlock my jaw now, and will be switching to another after this is accomplished. This board is really gonna be helpful for you, so keep us all posted! Hang in there, because I've heard a lot of good results with the tmj specialists who know what they are doing.
