Shoulder Pain On The Pacific Crest Trail - Page #4
 

Working Diagnosis:
Right long thoracic mononeuropathy

Treatment:
Rx: prednisone 50 mg daily x5 days (for possible neuritis)
PT referral:
Maintain shoulder range of motion
Strengthen intact scapular stabilizers
Avoid aggressive upper limb and overhead activities

Outcome:
Nearly 12 weeks after onset, medial scapular winging persisted without palpable contraction of the right serratus anterior, however, pain resolved. No sensory deficits or additional weakness developed. The patient returned to day hiking without a pack and started downhill skiing. He was counseled to avoid excessive poling during skiing. He will be monitored for recovery every 3 months with a plan to repeat electrodiagnostic testing if weakness persists.
