It is understandable to feel concerned, but bloody discharge often just means an ear infection has caused a small tear in the eardrum, which typically heals well on its own. Because your ear is bleeding, please do not use any over-the-counter ear drops yet, as certain drops can be harmful if the eardrum is open. For the pain, you can safely take oral pain relievers like paracetamol or ibuprofen. Please visit a doctor promptly so they can safely examine your ear. They can prescribe appropriate oral antibiotics or safe, prescription-only ear drops (like ciprofloxacin) if needed. Keep the ear completely dry.
