It’s understandable to feel concerned when symptoms like severe cold and ear blockage don’t improve after a few days of treatment. Cetirizine and ambroxol in Relent help reduce allergy symptoms and loosen mucus, but persistent ear blockage and cold symptoms may need further evaluation.

• Continue your steam inhalation as it helps relieve congestion.
• Do not stop or change your Relent medication without consulting your doctor.
• Since your symptoms have lasted 3 days without much relief, it’s important to see an ear, nose, and throat (ENT) specialist to check for possible ear infection or other complications.
• Watch for warning signs like fever, increasing ear pain, or hearing loss, which require prompt medical attention.

If you want, I can explain more about how these medicines work or what to expect next. Meanwhile, please consult an ENT specialist for a thorough assessment.To narrow down potential causes, we will need some more information.I understand that you have a bad cold and blocked ears, and that Relent and steam aren't helping much.
