Bird with blood around his mouth

Hello last night my bird was sitting on the bottom of the cage in the corner he is a cockatiel is is very much unlike him he looks so I'll. He was not eating or drinking usually he loves food. I was really worried I put him asleep hoping if was a mild flu and that tomorrow he would at least show signs of getting better, but this morning when I woke up he had bloo all around his mouth already dried and there was blood splatter all up the walls as soon as u woke

I immediately checked on him, when I saw him I was histerical I panicked I took him out he has not visibly hurt himself. So I phoned up our nearest vets and rushed him there straight away the vet seemed unsure. He gave him an injection and some antibiotics? He checked his tounge and he has not hurt his mouth but the back of the tounge seems sore?

The the vet examined him he hardly put up a fight, usually he would be biting and scratching. Could you please help me we have been given a weekly dose of antibiotics I'm so upset and scarred his only 6 years old I don't want to loose him so soon thankyou
