17 yr old. Keeps getting reoccurrnt laryngitis. Has chronic lymphoadenapathy throuout neck and sings all the time. Is this ok?

Hoarseness & nodes. If he abuses his voice with persistent loud singing without appropriate training, then this is probably the cause. But the combination of lymphadenopathy (i am assume multiple nodes in neck, some 1" or more in diameter) and recurrent laryngeal symptoms makes me concerned. I would recommend a check by an ENT specialist. These are not common symptoms at this age.
