Hi sir,
Foreign body sensation in throat is one of the most common complaints that bring patients to an ENT specialist.
If there is only FB sensation and no change in voice, radiating pain in ear, difficulty in swallowing or aspiration of liquid and solid foods, there is less chance of a severe problem.
It may be due to reflux or laryngo-pharyngitis.
Next Steps
Try some anti-reflux medication and warm saline gargle every day after waking up and before going to bed.
Health Tips
Its always better to consult an otolaryngologist in person and to do a diagnostic laryngeal endoscopy to rule out any other conditions.
