Many people experience hard bumps after vaccination because most preventive injections are subcutaneous injections, which can cause bleeding under the skin. Therefore, there are usually some hard bumps. In the early stage, you can use a cold towel or ice pack for cold compression, which can effectively alleviate the formation of hard bumps.
1. Especially after the vaccination, it is recommended to press the injection site with your hand to reduce subcutaneous bleeding and effectively prevent the formation of hard bumps later. If you want the hard bumps to disappear quickly after one day or the second day, you can use a warm towel for hot compress. However, please note that the warm towel should not directly contact with water as the injection site has not healed yet, and contact with water may cause infection.
2. However, it should also be noted that if there is persistent pain, hard bumps, or abscesses inside after the injection, it is recommended to consult a doctor in the hospital. It is not advisable to squeeze the abscess out blindly with your hands, which may also lead to infection.
3. Both adults and children should pay attention to post-vaccination care. After the vaccination, avoid immediate contact with water and avoid spicy and irritating foods. Focus on nutritional supplementation and observe for half an hour after the vaccination.
