Weaning woes! Is this normal?

I weaned my 18-month-old from breastfeeding completely 6 days ago after gradually reducing sessions over about 2 months. My left breast seems to be fine, no longer engorged at all and soft and kind of deflated, but my right breast is very engorged, lumpy, sore, and leaking milk. I don't think it's mastitis (yet) because there are no feelings of illness or hot spots on the breast. I'm not sure if it's a clogged duct or if this is just normal when you stop breastfeeding. I've read engorgement can last 5-10 days. The pain isn't really bad but it is sore and uncomfortable.

Any tips or suggestions for relief? Does this seem normal? Has anyone experienced anything similar?

Thanks!
