There doesn't seem to be any known reason for his ringing. He did not have an injury and has not been subjected to loud noise.

I called and left a message asking for direction with his primary physician. He said he's like to see him as well - so we are going there tomorrow. I read that anemia can cause ringing and so can a Vitamin B deficiency - so maybe they will do some blood work to see if if has either of those.

My husband has tinnitus and found using a combination of three herbs he came across on the internet helps him TREMENDOUSLY - but, herbs aren't recommended for kids - otherwise I'd start him on the same regime!

Thank you for your replies.
