What should I do if there is a lump at the injection site after vaccination?

When babies are just born, they will get some vaccinations to prevent the occurrence of diseases, which has a good protective effect on the body. However, most babies have lumps at the injection sites after vaccination. Parents will be very nervous and worried if they don’t understand, fearing that it will cause harm to the baby’s body. In fact, this situation is completely normal. Let’s take a detailed look at what to do if there are lumps at the injection sites after vaccination?

First, what should you do if there is a lump at the injection site after the vaccination? After the baby receives the vaccination, adverse reactions of varying degrees may occur due to different physical conditions. Mild cases may include local adverse reactions such as redness, swelling, heat, blisters and pain at the injection site. Severe cases may experience fever, headache and general discomfort after the injection.

Second, if there is a lump where the baby was vaccinated, parents should first confirm the condition of the lump. The range of swelling and lump at the injection site is divided into mild, moderate and severe. A mild reaction is less than 2.5 cm in diameter, a moderate one is between 2.5 and 5 cm in diameter, and a reaction greater than 5 cm is a severe reaction, which can last for several hours or days. If the child has a mild reaction, parents do not need to panic as it will not affect the child's health. If the lump is a severe reaction, then you must apply hot compresses and seek medical treatment immediately.

Third, the lump appears where the baby was vaccinated because the baby’s physique is temporarily unable to withstand the medicinal properties of the vaccine, so inflammation symptoms occur at the injection site for a short time.

Fourth, usually after intramuscular injection, a nodule will appear at the injection site, which not only causes a certain amount of pain to the patient, but also makes it difficult to continue intramuscular injection treatment and affects the effect of the drug. This is especially true for children, because their bodies are not fully developed, their muscles are not full, their blood vessels are small, their microcirculation is poor, and drug absorption is slow. Their muscle fiber tissue proliferates rapidly after acupuncture and drug stimulation, making it more likely for nodules to form at the site of intramuscular injection.

What should I do if there is a lump at the injection site after vaccination? Fold a towel or gauze into a square, soak it in hot water at about 60℃, take it out, wring it dry, and gently place it on the lump. Adjust the pressure according to the patient's age, constitution, and disease condition, based on the patient's tolerance, and then cover it with plastic film to keep it warm as much as possible. Change it every 5 minutes and continue hot compress for 20 to 30 minutes. You can combine it with local massage. Be sure to be careful not to burn the skin. This method can dilate local capillaries, promote the absorption of medicinal solutions, and promote the dissipation of nodules.
