Hi Maxinemm,
Welcome to our community! I'm so glad you found us.
If you haven't yet, it would be helpful for you to start with reading through the thread at the top of the forum titled,"New to Lyme?...Start here!!", as it is packed full of important information, symptom lists, helpful links and pdf's, how to detox when one has these infections, information on probiotics and much more.
And, here's another good place to find helpful detoxing routines:

Not many heal well on the Marshall protocol, due to the need to avoid Vitamin D, which unless the person has very high levels of Vitamin D in their body, it's a very necessary component of our healing.
I hope that your son's original doctor can be of help, but if not, please do let us know. We have a list of Lyme literate doctors and we can help you investigate other treatments as well.
Lyme can present as Tourette's:
