do we tell neurologist what we are doing?

I think it depends on whether they are 'on board' or not.

My PCP knows I am on long-term antibiotics, and being treated with a LLND.

When I got my Igenex positive test result, I showed it to her. She asked for a copy of it, and then said, "So, what do you want to do."
She is supportive, acknowledges that we aren't diagnosing and treating Lyme disease effectively here in Canada. She also gave me a standing order for lab tests to monitor my kidney and liver function.

If she wasn't supportive, I would hesitate in telling her too much.

You could tell your mom's neurologist that you're mom is getting treatment for lyme...but I don't think I would provide the details UNLESS the neurologist was receptive.

thanks guys. I probably won't for now then. Meanwhile, it's been a very stressful and emotional day for me, dealing with social workers, new doctors for my mom. I need a bit of a break

My family doc actually dropped me when I told them. I would hope this isnt the norm, but I suppose its best to brace yourself and weigh your options should you ever decide to fill your other doctors in.
