Scar tissue root cause ?

I believe the root cause of my pain after years of trying to figure it out is scar tissue has developed all over the right side of my face from my jaw injuries. The popping and cracking sounds were scar tissue and it was hitting nerves and all sorts of weird things. I have a ton of scar tissue particularly in my massatar and upper region near my ear. It is causing debilitating pain. I have been trying to break it up more but it feels so thick im not sure I can. I am working with it every day still in hopes to free more tissue and heal it with massage. I read it can take a long time to break up thick tissue that has formed. I am massaging it all day now. I am still taking ativan but want to eventually get off it in the near future.

The right side of my face is all hard and crepitus and the left is all soft which is the undamaged side.

Is there a surgery that can remove the scar tissue? I am aware this creates more scar tissue to rebuild but at least I can work with it better and massage it before it becomes massive like this again. I wonder if cortisone injections would work as well.
