Talk to Pediatrician on Torticollis

I have a 18 months old son, and he is having torticollis. Now going back when he was 6 months old he had a tilt at that time too, he had multiples physiotherapy sessions like 15 to 18 sessions plus i used to do at home as well, and like after few days his neck was fine. Now from past 2 weeks i have been noticing the tilt again. Kindly post on my behalf and connect to me some good physiotherapist. Help a worried mother. Thankyou so much.
