Constant need to clear my throat
You feel a tickle at the back of your throat. So you clear it. A minute later, the urge is back.
Most often this comes from mucus sliding down the back of your throat. Your nose and sinuses make mucus all day long. When it gets thicker, or there is more of it, you start to feel it.
Colds, allergies, dry air, and smoke can change that mucus. Acid rising from the stomach can cause the same tickle. So can some blood pressure pills.
When to see someone
See a doctor if the throat clearing lasts more than three weeks. Get checked soon if you cough up blood, lose weight without trying, feel a lump in your neck, or find it hard to swallow. Go the same day for trouble breathing, a high fever, or a hoarse voice that will not clear.
