What are the methods to reduce injection pain?

To reduce injection pain, methods include selecting appropriate injection sites, optimizing injection techniques, providing psychological counseling before injection, controlling medication temperature and concentration, and using proper pressing techniques. Scientific application of these methods can effectively reduce pain. If persistent redness, severe pain, or allergic reactions occur after injection, prompt medical attention is recommended.

1. Select an appropriate injection site: Prioritize areas with abundant muscle and fewer nerves and blood vessels, such as the upper outer quadrant of the buttocks or the deltoid muscle of the upper arm. Avoid joints, scars, and indurated areas to minimize nerve stimulation and tissue damage.

2. Optimize injection procedures: Fully expel air before injection; insert the needle quickly and steadily; inject the medication slowly and evenly, avoiding sudden acceleration or pauses to reduce local tissue irritation from the drug.

3. Provide pre-injection psychological counseling: Explain the injection process and possible mild discomfort in advance to alleviate anxiety and tension. This helps prevent increased pain due to muscle tightness. Deep breathing and distraction techniques can assist in relaxation.

4. Control medication temperature and concentration: Allow refrigerated medications to warm to room temperature before use to avoid cold-induced irritation. Dilute high-concentration medications as instructed to reduce local tissue irritation and minimize pain.

5. Use correct pressing technique: After injection, apply a sterile cotton swab vertically over the puncture site for 5–10 seconds with moderate pressure. Avoid rubbing to prevent leakage of medication or local bleeding, thereby reducing subsequent swelling and pain.

After injection, keep the area clean and dry to prevent infection from moisture exposure, and avoid strenuous activities that strain the injection site. If minor nodules develop, appropriate warm compresses may help promote absorption. Complete all follow-up injections as prescribed by your healthcare provider.
