Wide spectrum: Possibilities include: Minor trauma (scratch) from a sharp food particle, a lesion caused by a virus or bacterial infection, a tiny fish or chicken bone fragment, or rarer lesions such as a tumor (benign or malignant), an irritation from chronic exposure to smoke or alcohol, or from exposure to other toxins. The list is extensive.
