The occurrence of arm discomfort during or following a forceful expulsion of air from the nose and mouth is not typically a direct physiological consequence. Sneezing primarily engages muscles in the respiratory system, diaphragm, abdomen, and face. The sensation of pain or ache in the arms is therefore likely related to secondary or indirect factors.
Understanding potential underlying causes is important for managing any associated discomfort. While infrequent isolated instances are likely benign, persistent or worsening symptoms warrant medical evaluation. Identifying the specific mechanism at play allows for targeted interventions and potentially prevents escalation of an underlying condition.
