I hear your frustration. My thinking is why not see a qualified chiropractor, MANY work with children from birth. I would not use the drugs, they have their potential side effects and can cause more issues than one already has.

Hope you will find down the road the root of her pain and work in a more natural manner.

I've never taken gabapentin but I think one has to withdraw slowly. Not sure.

So many chiropractors have gone on to work holistically and that is what I'd be looking for if it were my child.
