Hi and welcome to HCM.
Peribronchial thickening is nonspecific sign,usually means nothing, but can suggest bronchitis
especially in smokers. I would be more concerned about this spine issue? it must be evaluated by Ct scan
. it can be degenerative changes but something muxh serious should be ruled out. You should also do liver and gallbladder
ultrasounds to check gallbladder stones,this can cause such pain too. Wish you good health.
