Torticollis + reflux

I am new here. My dd who is almost 4 mos old has reflux. The GI specialist has only prescribed zantac 1.5 ml 2x a day. She had been doing pretty good on it for the last two months. She is generally a happy baby as long as you remember her zantac on schedule doesn’t even mind her spit ups much. Then I realized she had a severe left head tilt. So we started exercises for torticollis not thinking of a relationship between the two even though I had heard of it before.

Well a week into the exercises she is definitely turning her head to the affected side more easily and holding it up a little straighter. Problem is she is cranky as heck. Arching like crazy and hating her carseat again, waking up after 30 min of sleep when normally she will nap for an hour and a half to 2 hours.

So my question is do you think the head tilt was making her reflux more comfortable and now that we are making her hold her head straight the zantac just isn’t enough? Does it stand to reason that if the reflux caused the head tilt and torticollis that straightening the head tilt makes the reflux restart again?

And if so what can I give her. Our GI and Pediatrician are terrible refuse to give me prevacid solutabs, no idea why, they wld rather her be in pain. Can I use prilosec capsules and sprinkle them on as soon as she starts cereal? I am desperate I want her head straight but I want my happy baby back too!
