Severe pain in one ear can happen for several reasons, including ear infection, wax buildup, throat or sinus infection, pressure changes, jaw joint problems, or irritation inside the ear canal. Sometimes the pain may come and go, while in other cases it may be associated with blocked sensation, reduced hearing, ringing sound, or discomfort while swallowing. Ear pain can also occur after a cold, allergy, water entering the ear, or travel to high-altitude places. Mild pain may improve with rest, avoiding water entry into the ear, steam inhalation if you have cold symptoms, and keeping the ear clean and dry. Avoid putting earbuds, oil, pins, or any sharp object into the ear, as this may worsen the problem or injure the ear canal. Since you are experiencing severe ear pain, it would be a good idea to consult an ENT specialist, especially if the pain keeps returning or becomes intense. The doctor can examine the ear properly to check for infection, wax buildup, pressure problems, or other causes and suggest the correct treatment. Seek medical attention promptly if you develop fever, hearing loss, dizziness, swelling, discharge or pus from the ear, severe headache, or persistent pain lasting more than a few days. Early examination usually helps prevent complications and provides faster relief.

Since the combination drops did not provide relief, the itching may be due to ear canal eczema, dry skin, or a persistent fungal infection. I highly recommend consulting an ENT specialist to examine your ears safely. Meanwhile, keep your ears completely dry and avoid using cotton swabs, which can worsen irritation. Depending on the diagnosis, a doctor may prescribe mild steroid drops (such as fluocinolone acetonide) for inflammation, or specific antifungal drops (like clotrimazole or acetic acid solutions) after professionally cleaning the ear. Please avoid starting new ear drops until a doctor has examined your ears to ensure the eardrum is intact.
