What do you suggest if my mum supposedly has torticollis, but why does she have chest pains?

See her doctor: Torticollis is a condition in which the head is tilted, often due to neck pain/spasm in the muscles that move the head. However, it should not cause chest pain. Please take her to the doctor soon - immediately if she has difficulty breathing, worsening chest pain, pressure, pain in her left arm, sweating - or looks like she does not feel well.
