Great clinical question. Since you have taken the foundation course at this point, you are needling the correct neuroTrP. To add to what you’re doing, you may also include the hyoid muscular needling learned in the 1st level course since you do get into the facial nerve innervation zone (innervation to posterior digastric). The advanced course (2nd level) provides needling techniques that include the extracranial points of the facial nerve (where it exits the stylomastoid forament) and the 5 branches (temporal, zygomatic, buccal, marginal mandibular, and cervical).
