No, I didn't think of that. I hope she didn't get hit there. It almost seemed to be going down last night. I guess she could have climbed a tree and fell off while browsing on Saturday. She is kind of clumsy and has done that kind of thing before.
I remember you mentioning in another thread that she didn't really care for you touching it. That made me wonder if it's tender and that made me think maybe hematoma. Just a fleeting thought, lol.
Even if so - it'll probably re-absorb just fine and really nothing else to do but wait.
