Hi mocasey. I am sure it is frustrating to be so far from your mom
You are a big help to her.
It sounds like the Doxy is targeting the Lyme. It is normal to feel worse before feeling better and for symptoms to migrate. She really needs to be on a higher dose. Will she being seeing the Lyme doctor in NC? She needs to be tested for the co-infections. What lab was here Western Blot test done at and which band was positive?
The symptom journal is important. She could document the three worst symptoms of each day with a numerical rating (between 1-10) of their severity. This journal helps tremendously over time.
Thanks for the well wishes!
