###Human: Will post nasal drip cause a whitish lump in throat? ###Assistant: Hi. I understand your concern, it is most likely submucosal lymphadenitis of the posterior pharyngeal wall. This may develop secondary to chronic infection of the nose, paranasal sinuses, and throat. To confirm the diagnosis, you may go for MRI neck and FNAC from the lump. Most of the time it is reported as non-specific reactive hyperplasia which is not a problem and maybe leave as such but if anything special comes in FNAC then that may be plan for treatment accordingly.
