Stopping ebf “cold turkey”

I’ve been in the hospital for over a week with a ruptured spleen that I had to get removed. I pumped a couple of times per day for 3 days (still not nearly enough) but had to dump due to the extreme meds I was on. I had surgery on day 4 and haven’t pumped at all since (today is day 7, but I just got home). I decided due to my pain and where my incision is that I’m going to switch to formula (my freezer stash was used up until last night when I ran out). I never once felt full or engorged or in pain, but I was also on big pain meds. Now I’m home and only on Tylenol and I feel engorged and sore. I’m not allowed to pick up my son, so that also makes bf difficult. But my question is, what should I do about my full breasts? The pain meds should probably be out by tomorrow, but I’m not sure if I want to pump again, but I’m also very sore. Suggestions please.

Edit** my son is 9 months old, if that matters at all
