For children with allergies, their quality of life is also affected by actions of their peers. There is an increased occurrence of bullying, which can include threats or acts of deliberately being touched with foods they need to avoid, also having their allergen-free food deliberately contaminated.

Phonotrauma subjects the vocal folds to excessive mechanical forces during these vibratory cycles, which can lead to the development of a wound. It is the healing of these wounds, which leads to tissue re-structuring, that can result in a vocal fold cyst. Diagnosis
There are generally four components included in the full diagnosis of a vocal cord cyst: a medical and voice history, a head and neck exam, a perceptual assessment of the voice and imaging of the vocal folds. A medical and voice history can help distinguish patterns of misuse and phonotrauma to assist in diagnosis. The primary perceptual sign of vocal fold cysts is hoarseness of the voice. Diagnosis through perceptual means alone is difficult, therefore in the fourth component of diagnosis the patient often undergoes an imaging procedure. Imaging is most commonly done with laryngeal videostroboscopy. A videostroboscopy is an examination of the vocal folds using flashes of light to slow down the image of the vocal fold movement enough to provide a sharp picture of the phases of the movement cycle (mucosal wave.) This procedure provides information about vocal fold vibrations during speech, vocal intensity and vocal frequency. Imaging shows the reduced movement of the vocal folds (mucosal wave) when a vocal fold cyst is present. Further, videostroboscopy tends to show increased submucosal swelling in the affected areas of the vocal fold(s) More recently, other technologies have been introduced to assist with obtaining imaging of the vocal folds, including the use of Narrow-band imaging (NBI.)
