Nine-valent generally refers to the nine-valent cervical cancer vaccine. You can raise your arm, soak your hand in hot water or take a hot bath to relieve the arm pain after injection, and actively consult a doctor if necessary.
1. Raise your arm: when you have arm pain after taking the vaccine, you can raise your arm to change the blood circulation, which can relieve the pain to a certain extent.
2. Soak your hands in hot water: you can use hot water to soak your hands, which can accelerate the local blood circulation and relieve the symptoms of pain.
3. Hot water bath: 24 hours after the injection of the vaccine, you can take a hot water bath, which can also improve the symptoms of pain.
If the above treatment does not relieve arm pain, you need to carefully observe whether the arm is red and swollen. If there is redness and swelling, it is possible that the pain is caused by infection, and you need to go to the hospital in time and do the corresponding treatment under the guidance of professional doctors.
