Hope she's ok! A lot of new bird owners are scared by a 'lump' on their bird's back that turns out to just be their elbow. They have very bony little elbows. I'd feel again and see if there's a matching lump on the other side.
I don't see any blood in the photos - well not any blood that isn't where it should be, lol. What you show looks like a normal blood feather with a blood-filled shaft. Was it actually bleeding earlier? It's normal to see the blood in them, especially with those light colored flight feathers, but that's just how the feather develops. Once the feather grows in fully, the blood supply dries up and it will look like her other feathers. Nothing should be done unless it's actually damaged and bleeding.
Also, a little flaking of the beak is normal, and also not something to worry about. The beak is bone covered with keratin that grows constantly (like your fingernails) and flaking and peeling is normal. But, actual beak injuries that damage the bone are very painful and can become infected or cause the beak to grow abnormally, so if it's a large beak injury, then a vet would be needed. A serious beak injury is rare unless a bird is bitten by a larger bird, or falls or flies into something pretty hard. 90% of the time when someone's worried about a chipped beak, they are just seeing the normal flaking on a healthy beak.
