Hi Imz,
Welcome to HealthcareMagic Forum,
The foreign body sensation in the throat in the absence of pain or
fever can be because of laryngo pharyngeal reflux or granular pharyngeal wall.
Laryngopharyngeal reflux occurs secondary to reflux of acidic contents from the stomach. Granular pharyngeal wall can be secondary to recurrent
throat infection. I would advice you to drink plenty of warm water, avoid oily/spicy food/coffee/tea for few days. If the problem persists please consult a good
ENT specialist.
