Median nerve neural mobilization, non pharmaceutical, non invasive, physiotherapy technique; which consists of a passive and repetitive upper limb movement that seeks to induce median nerve gliding and incursions against surrounding connective tissue. Subjects will be treated 5 days per week during a total time lapse of 2 weeks. This arm will also receive an oral ibuprofen arginine pharmaceutical treatment. Participants will be treated with a maximum of 1200 mg per day, subdivided in 3 intakes of 400 mg each 8 hours during a time lapse of 2 weeks

Assessed through the visual analog scale (VAS). The VAS is a psychometric response scale. It is a measurement instrument for subjective characteristics or attitudes that cannot be directly measured. The VAS is the most frequently used method to assess pain intensity. The scale will be displayed as a horizontal 10-cm line labelled at each end by descriptors such as 'no pain' (the minimum and best outcome possible) and 'worse pain ever' (maximum and worst outcome possible). The participant will mark the line to indicate pain severity and it is simply quantified by measuring the distance in centimeters from 0 (no pain) to the patient's marked rating.

Assessed through the QuickDASH questionary, which is a shortened version of the 30-item DASH (Disabilities of the Arm, Shoulder and Hand) instrument.The instrument administered to the participants will be a self-report questionnaire, that will rate the difficulty and interference of daily life on a 5 point Likert scale. At least 10 of the 11 items must be completed for a score to be calculated and the scores range from 0 (no disability) to 100 (most severe disability).

This measure is performed through the employed participant (full-time or part-time) answering in a dichotomous manner (yes or no) the question: "Do you currently work?"
