Drains and explant surgery: is it normal for one side to be more swollen and feel worse than the other side?

I had my explant surgery one week ago and had drains in or 3 days. The left breast is absolutely fine however I'm still having discomfort with the left side where the actual drain entered my breast. There is no gunk or leakage , it just feels slightly more swollen than the left side again where the drain entered the breast. Is it normal to have one side worse than the other? This side that's painful still was the Breast that was draining more fluid out of the two of that means anything?
