migrains and Benign Paroxysmal Torticollis

My daughter was diagnosed with Benign Paroxysmal Torticollis when she was a baby.
She would have recurring head tilts and she would vomit.
The head tilts passed when she was 3 though she still tilts her head a lot.
She is now 13. Since she was five she has benn suffering from stomach and head aches. For the pas 2 years she has had recurring head aches punctually every 2 months. The head aches continue for 3 to 5 days with vomitting.
Paracetamol and Adville don't help her and even Optalgin drops don't help.
All neurollogy tests and MRI were O.K.
Is this connected to the BPT and how can we treat her.
Thanks for answering,
Chen's Mom

you could try an anti-histamine drug for migraine e.g. sandimigraine, periactin etc
