Stiffness in Clavicles

Anyone ever experience extreme clavicle stiffness that radiates into the neck and persists for months? I’ve read a few posts here on AC joint injuries, and I’m wondering if that’s my issue.

The clavicle stiffness bothers me most when doing pull-ups or lat pull downs. I literally feel something clicking near my sternum as I pull the bar down. I did pop a rib out of my sternum playing football when I was a kid, but it hasn’t bothered me in years. The pain feels almost like my upper pec muscles are squeezing my clavicle- sort of the way shin splints feel, but on my collarbone instead.

I haven’t been to a doctor in 13 years because I don’t like paying $300 to have some greedy ignoramus give me a script for some pills that will cost me another $120 and cause side effects that are worse than what I’m treating. I’d rather home remedy injuries like this one.
