How to quickly reduce swelling after an injection

Generally, hand swelling after an injection can be relieved through appropriate rest, cold compresses, heat therapy, elevating the affected limb, and medication. Specific measures are as follows:

1. Moderate rest: After receiving an injection, the hand should be given adequate rest to avoid overuse or frequent movement, which may worsen the swelling. Keeping the hand still helps reduce local circulatory strain and promotes resolution of the swelling.

2. Cold compress: In the early stage after the injection, apply an ice pack or cold compress to the affected area. Cold therapy constricts blood vessels and reduces local blood flow, thereby alleviating swelling and pain.

3. Heat therapy: Once the swelling begins to subside, warm compresses using a warm towel or hot water bottle can be applied. Heat dilates blood vessels, improves circulation, and accelerates the absorption and dispersion of inflammatory substances.

4. Elevating the affected limb: Elevate the affected limb above heart level to help reduce venous return and minimize swelling. Pillows or blankets can be used to prop up the hand comfortably.

5. Medication: Under medical guidance, topical medications with anti-swelling properties—such as Yunnan Baiyao aerosol spray or safflower oil—may be used to promote blood circulation, resolve stasis, reduce swelling, relieve pain, and speed recovery.

During recovery, maintain a balanced diet and consume adequate vitamins and protein from sources such as broccoli and eggs. Avoid strenuous exercise to enhance immune function and support overall healing.
