Her lump

Lump, day 7 (exactly one week post vaccine) - feels fluid filled yet we weren't able to get anything out of it at the vet.

Lump, day 11 - lump turned hard (like cement), and it was obvious that it was her skin that was hard and not something else.

Lump, day 13 - visibly smaller! Started second course of antibiotics, still on anti-inflammatory, also continuing warm compresses w/ heating pad twice/day. No longer feels like cement, but is hard.
We have major progress -- thanks for everyone's concern and prayers.
