Participants in this group will receive intramuscular (IM) injections of premenopausal or postmenopausal hormonal medications. Immediately prior to the procedure, the Shotblocker device (a plastic, butterfly-shaped tool with blunt contact points) will be applied to the gluteal muscle injection site following aseptic techniques. The device will be pressed firmly against the skin to saturate the sensory signals through the gate control mechanism. While the device is in place, the IM injection will be administered according to standard clinical protocols. The device will be removed once the injection is completed and the needle is withdrawn.

Participants in this group will receive intramuscular (IM) injections of premenopausal or postmenopausal hormonal medications. Prior to and during the injection, the Helfer Skin Tap (HST) technique will be applied. This involves rhythmic, gentle tapping with the fingertips on the skin surrounding the gluteal injection site. The tapping starts just before the needle insertion and continues rhythmically to promote muscle relaxation and utilize the gate control theory of pain management. The IM injection will be administered according to standard clinical protocols while maintaining the rhythmic tapping.
