Maybe keep a small pillow over your collarbone area? Especially if you have a buckwheat or microbead one that molds to the shape of whatever you put it on.
I had abdominal/pelvic surgery with a cat who loved walking across my stomach, so while I was recovering I never lay down without a pillow covering my incisions. When she did step on it, the pillow at least helped disperse her weight so it didn’t hurt much.





According to OP’s comment in the original post, yes, that’s exactly what it’s supposed to look like. The gauze just has some food coloring to make that joke.
