So glad I went for another opinion. I went to a pedi PT, and found out that the stretches/exercises that the first one gave me were all WRONG. Everything was backwards, like the stretches were for the wrong side of his neck! I figured that out after our first meeting with him, and that is why I went to the chiro afterwards.
Anyways, it's not true torticollis that he has. It's mainly a weak muscle on the right side, and the left is a bit tight. She was very good at explaining everything, and I learned the correct way to be stretching and strengthening his muscles.
We go in next week for a follow-up.
