Left Trapezius  2 x 7.5-10 u Max 50 u Botox;  2 x 30-40 max 200 u Dysport

The trapezius is superficial and is generally easily palpated at the base of the neck palpate. It is likely that the trapezius does not play a major role in causing abnormal head posture, but the muscle often seems to cause pain, which is effectively treated with botulinum toxin.

Recommended to inject trapezius at the base of the neck with one or two injections.
