Collarbone issues?

I am so excited to start my hike in May! I have a fair amount of backpacking experience, but I’ve never done a thru. I have hardware on my collarbone and about 9 screws from an injury 6 ish years ago. This has been slightly uncomfortable for me with heavier backpacks in the past. The other week, I did a hike with my backpack (with more weight than I plan to hike with) as a training hike and I had a slight bruise on the skin above one of the screws. Like I said, I’ve dealt with this on shorter trips, but I’m curious if anyone has had a similar issue and what their solution was. Makeshift padding? Better backpack weight distribution?

I’m also researching lightweight backpacks atm, so backpack recs with hardware friendly straps is also appreciated!
