Hi fastinjun,
Welcome to the forum! It think you will find our members very helpful and knowledgeable.
So sorry to hear about
your son's food allergies, that is a great worry. It could be caused by Lyme disease, so it would be good to rule that out or treat it.
If you need help finding a Lyme Literate Doctor, please let us know. You will need to see someone who is experienced with treating children.
I'd like to direct you to the website
www.drjoneskids.org. It is a great resource.
Also, have a look at our "New to Lyme?" thread. It will help you get started on your research.
