your treatments sound good. I had the laser by my chiropractor done on my ankle ( Trimalleolar - all bones broken and foot/leg separated).
He did it to speed up healing of the foot. It did relieve the pain somewhat (which is still here - 5 years later). He combined it with heat and traction/stretching. Felt so good afterward
I had not heard of the needling. Sounds like you at least have a little room for hope for improvement.
