Without having the guitar in front of us, we are all just guestimating the process.

Nothing worse than a rattly truss rod.

I have at times, where a truss rod has been placed into tension and it still rattles, removed an inlay drilled down to the location of the rattle and repotted the truss rod at this location.

The point it can be rectified, you would however need to visit someone local to yourself to identify really what it needs.

From your description, I am assuming the truss has been wound off to nothing, so you have lots of relief at the 7th to 9th and then start choking out around 10th onwards, then the action is still to low for your playing style, with a raise of the saddle and the bringing on of the truss rod, it may all be resolved, but again this is just a guestimation hence the advice of seeking someone local to you.
