The last two weeks i seem to keep gagging, not when eating or drinking. it's just out of the blue. what could this be?

Maybe LPR: Exposure of the vocal cords to stomach acid & pepsin may result in inflammation of the vocal cords occurs with larygopharyngeal reflux (LPR). Acute laryngitis may result, but watch out for chronic hoarseness, gagging, throat clearing, airway spasms, bronchitis, an asthma-type presentation, and even a higher risk of throat cancer. Impedance ph testing with symptom diary may best characterize this.
