Held her again this morning before work, no change in mood or disposition.

Also what I meant by the lump is not hard, is that its not hard or sharp or anything. When touched or when the she crawls over my hands her skin / body still conforms to what she is on, goes away temporarily then is visible again with nothing under her. You can touch it without it feeling any different than the rest of her body. No reaction at all to touching it.
