Effect of Skin Stretching on Pain Reduction During Local Anesthetic Injections: A Randomized Clinical Study

A conventional infiltration anesthesia will be conducted on the lumbar area of the patient, targeting the epidermis and subcutaneous tissue. A 25G syringe will be used, with the needle angle set between 30° and 45°. 1cc of 1% lidocaine will be injected. The target size of the wheal is 5-10 mm.

Skin stretching techinique will be applied to the local anesthetic injection site by stretching the skin around the needle entry point.
