Thank you for the input! The feeling of compression I feel is constantly there when I breath and also is making speaking difficult, I feel something stuck under the rib when I try to speak with force, so it definitely doesn`t feel like something should be happening. When I apply a force to that rib, I can feel something on the lumbar feels discomfort and "compressed", and the location does seem to correspond with the old L2 fracture.

I have been thinking about kyphoplasty but I have no idea if it would help in my case, and many doctors don`t want to do it on an old fracture it seems.
