​"I have been suffering from a mild dry cough for a long time, and I hear a sharp sound in my throat while sleeping at night, which makes me feel a bit short of breath. My eyes itch a lot throughout the day, and occasionally I have a runny nose. If I take a steroid tablet, I stay fine for several days. I have previously consulted a doctor who said it is mild asthma. Is there any permanent treatment for this? Please help me."
