Welcome here! So very sorry about
your son. A mother's worse nightmare is an ill child.
First, I have to say, I am a huge fan of the Beyond Balance products. So there is a vote for the LLMD.
I don't believe that 18 days on anything kills lyme. So there is a vote against the chiro.
You can google and learn to do Kinesiology or muscle testing yourself. I'm not a fan but gosh if I didn't do it and saw how it worked on me doing it on myself! So why not learn this yourself and test your son? Save a few bucks at the same time.
I love Buhner's teaching and here is his list of herbalists he recommends. You will have to call and ask if they do muscle testing. But with any of these I know you will get a good herbalist with what better recommendation than by Buhner himself.
buhnerhealinglyme.com/resources/herbalists/We don't put doctor's names on this forum in order to protect those that are in states where their practice could be in jeopardy for treating chronic lyme disease. We generally use initials.
Also, if you would like personal references, it would be helpful if you enabled your email address. To do that, you go to My Profile and bull's eye enable email and don't forget Submit at the bottom of the page.
Finally, we do suggest that new members read the first thread entitled New To Lyme. It is so super full of information. I still go there for references. You don't have to read it all at once. It can seem overwhelming. Just glance at the posts and see if they apply to you.
Again, welcome and keep asking questions. We all were new here once and now we are here to help.
