The neurologist said we have hypertonus. She said it's not scary, but massage is still worth getting. We booked a massage and the masseuse was so rough, hard, she did it all wrong! The baby cried and sobbed, and she kept turning his neck, bending him in half, and twisting his hands. I couldn't take it anymore, almost cried myself. We never went back to her. I want to know if this is normal or just a bad masseuse?
