Oh goodness! Definitely listen to your body!
When I was doing JRD90, I had a slowly healing torn rotator cuff - I was able to do pushups within reason, but I absolutely could NOT do pullups or chinups. So, I looked for alternatives - in my case, I did single arm rows with dumbells. I still got a good workout without further damaging my shoulder or impeding its healing. Maybe you could find something like that - an safe alternative exercise - for your pec muscle?
