Ear infections, whether bacterial or viral, can cause pain, pressure, and hearing loss. They often result from Eustachian tube blockage due to factors like allergies or colds. Complications include hearing loss and more severe infections. Treatment ranges from home remedies to antibiotics or surgery in persistent cases. Seek medical help if symptoms persist, especially in children with high fever or drainage. Prevention involves hygiene practices and avoiding risk factors. If you suspect an ear infection, consult a healthcare professional for proper evaluation and guidance.
