Thanks for the hugs. I did call -- no answering service and nothing special about Memorial Day. The website does list several local emergency places, but (reading online) such measures don't seem to be called for, and I'd rather see the vet who has the history on this.

Nala's a little better today -- oozing again, which is probably easier on her than pressure continuing to build up in the lump. We're doing warm compresses.
