The Value of Standardized Respiratory Rate Monitoring Exercises During Rheumatological Injection Procedures

The goal of this clinical trial is to demonstrate the non-inferiority of standardized breathing control exercises on perceived pain during rheumatological injections procedures compared to standard care consisting of the addition of a local anesthetic. The study population will consist of patients scheduled to undergo therapeutic ultrasound-guided joint or periarticular injection. The main question it aims to answer is: * Non-inferiority of breathing exercises compared to the addition of local anesthetic on pain and anxiety experienced during an infiltration procedure. * Correlation between the reduction in pain and anxiety experienced during a procedure and the cardiac coherence score obtained. Researchers will compare the anesthesia group (Arm A), which will receive local anesthesia with 5 cc of lidocaine before the infiltration procedure to the breathing group (Arm B), which will receive instructions before the injection procedure on how to perform 5-minute breathing cycles to facilitate the achievement of cardiac coherence to see if the pain perceived in Arm B is not greater than the pain perceived in Arm A. Participants will be kept blind to their randomization group. Arm A (anesthesia) will receive SHAM breathing exercises, while Arm B (breathing) will receive a placebo injection of anesthetic.
