Wow.... talk about varied response. I'm a "hit all targets" kind of person. So here they are:
Personally I wouldn't be TOO worried, but I would probably get it looked at, because if I'm worried at all I believe it's worth alleviating the worry. I would skip the psychiatry/psychological/spiritual (or at the very least save them for dead last) for the following reasons:
1) If it's spiritual, no biggie, spirituality in it's many forms is comforting and many people experience spiritual phenomenon. Since it's bothering him, that would suggest NOT spiritual. Perhaps more to the point... it also since it came from an illness. Eliminate the obvious, before looking for lost car keys in the neighbors chimney.
2) This didn't come out of nowhere. It came out of a flu. Direct causal relationship, indicating a PHYSICAL problem, not a psychological one. You son started hearing voices when he was sick. Any really GOOD psychologist/psychiatrist actually has their patient undergo a full physical workup BEFORE treating a psychological symptom. One of my profs used to say that she would lose at least 2/3s of her clients before they were ever really her clients, because during the workup a physiological cause was found. As extracredit one test she had us list out all of the differentials we could think of that would "snatch" a client away. The AVERAGE number of valid reasons for that extra credit problem was over 100 answers. Here's my brainstorming for just 2 minutes on physiological causes for hearing voices (and I'm not even a doc, merely a student).
Possible causes:
- hallucination (auditory)... caused either by fever or infection
- hallucination (auditory)... caused by sleep dep (sleep dep can bring on stronger hallucinations in most people than LSD)
- hallucination (auditory)... caused by an allergic reaction to medication he was on for the flu (and my Sis is allergic to tylenol... she hallucinates BIG TIME... visual/auditory/physical hallucinations, I'm just slightly allergic to naproxen, visual hallucinations, emotional reaction, & hydrophobia.). A person can literally be allergic to anything on the planet, and can *become* allergic to anything at any time. Most allergies actually come on gradually, the big anaphalactic shock leading to death type allergies are rare. Many allergies manifest themselves in the early stages as mild hallucinations.
- delusion... caused either by fever or infection
- inflammation of his auditory processing center (his brain misinterpreting the signals being sent to it from his ears
- inflammation or infection of the ear/nerves (the parts leading to his auditory processing center)
- inflammation or infection of any of the emotional centers of the brain
- inflammation or infection of any of the higher thought processing centers of the brain
All of the "inflammation", "fever", or "infection" causes have about 50 causes each... which would be pointless to list.
So see a medical doctor and here is what you tell them:
"My son started hearing things when he had the flu. I don't know if it was caused by an infection or fever or a reaction to his medicine, but it's continuing to persist even through the flu appears to be over... which is understandably making us scared."
Avoid the phrase "hearing voices" in the initial consult, because that's too loaded a phrase. They'll ask what he's hearing... and that's when you say "voices, sounds, things that are disturbing him." They'll be able to do a workup at that point (step one is changing any and all meds he's on... although they probably won't tell you that until the end, because step 2 is examining him for signs of continued infection -swollen glands, blood & urine tests etc. It's like in cooking you don't go to the store buy meat, cook meat, wait until it's finished and then go to the store buy potatoes, cook potatoes, wait until it's finished, and then go to the store buy veggies, cook veggies...and then however many hours later put a very cold dinner on the table. You look in the pantry & fridge first, go to the store & buy what you need, and then start cooking in the best order.
3) Someone mentioned "interior dialogue". Huzzah!!! When we're sick, our inhibitions/thought processes alter. If it was noisy or if there was something noise wise bugging him it would be totally rational/expected for his inner voice to be shouting at the world to be quiet, or to shut up. Adults usually act on that voice and shout at people/objects when they're sick... or know that it's their own mind surfacing from the "fog" because of some irritant. Kids, however, are fairly new to the whole interior dialogue... because they tend to be so impulsive that the "quiet voice" doesn't even have time to say "I shouldn't jump off the stairs because it could knock over x, mom will get mad if I knock over x, and even if it doesn't it's going to make a BIG sound." They're usually midair when those thoughts click... and it culminates in one word "Uh-oh". When they're sick though, they have the same lethargy that we do... since they're incapable of moving quickly those thoughts have time to formulate.
So that's my spin & differential, backwards.
1) Interior dialogue ... if I thought it was more than interior dialogue move on to #2
2) Physical reason ... auditory hallucination (or delusion) brought on by fever, infection, inflammation, allergy, or underlying physiological problem. If 30+ tests later yeilded no results (unlikely) move on to #3
3) A psychological problem or spiritual benefit... but all else would have to fail first.
All my best,
