I'm not a doctor and don't know your daughter's specific symptoms. However, check out Tinidazole. It is much easier to tolerate than Flagyl. It is used for BV and Trichomoniasis.
The downside is that Tinidazole and Flagyl are considered "cyst busters." If your daughter has Lyme, it may stir things up. However, if she has an infection, it should be treated. I think she should get a second opinion.
Here's some info:
