Why isn't antibiotics working for my throat and ear pain?

Your symptoms seem to suggest that you have allergies. Different symptoms including a runny nose, sore throat, and an itchy ear can characterize allergies. Dust, pollen, or keeping pets are the causes of these symptoms. It is important to keep your surroundings clean, use air filters, and take over-the-counter medication for allergies. Stay away from strong scents and consult your doctor for other treatment alternatives.

Your son has enlarged tonsils, he slows down when sick. These can make the throat hurt, make it hard to swallow, or even block some air. Helping him stay comfortable might include giving him lots of things to drink and soft things to eat. Make a doctor’s appointment if he seems very uncomfortable or it’s hard for him to breathe.

Very often the bloody nose is caused by some things i.e. dry air, allergies, infections, and high blood pressure. In different scenarios, anemia may bear a more long-term consequence including blood disorders or even tumors. You are advised to see an otolaryngologist for a thorough examination as well as opt for the recommended treatment.

Lymph nodes are small defenders in your body that help fight infections. Sometimes, they stay a little swollen even after the infection is gone. In your case, the nodes are small and movable, which is a positive sign. Since they haven’t changed in size over the past two years and aren’t causing any issues, it’s likely just your body’s way of managing past infections. However, it’s a good idea to keep an eye on them. If they grow, become painful, or new symptoms appear, it's best to get them checked again for peace of mind. 

The swelling and firmness you are having might be due to the soft tissue damage or inflammation due to the trauma. It is necessary to be cautious about these symptoms, as they might last for some weeks. To promote adequate healing and eliminate any unknown issues, I advise you to make an appointment for an extensive assessment.
