Usually, vaccination may cause pain and swelling at the vaccination site, weakness of the vaccinated limb, muscle aches and pains, which may be related to factors such as irritation of nerves or muscles by the ingredients in the vaccine and malabsorption of the drug, and often disappear in about 1-2 days. Patients with persistent vague pain for 1 month should seek immediate medical attention to clarify the cause and then actively treat it. To avoid adverse reactions to vaccination, patients are often advised to avoid bathing, swimming, and other activities that expose the wound site to water on the day of vaccination. This is mainly because the water in swimming pools may contain more microorganisms that can enter the body through the injection site and cause infection. Chemical agents in toiletries during bathing may also irritate the vaccination site and cause local swelling and pain. If the above mentioned triggers are not avoided in time or treated in time, it may lead to persistent hidden pain in the wound. In addition, strenuous exercise, staying up late, emotional excitement, or eating a spicy, stimulating, or greasy diet, as well as smoking and drinking alcohol after vaccination may cause adverse reactions after vaccination and aggravate the symptoms of hidden pain at the vaccination site. At the same time, if the patient has a long-term bad diet or irregular life, it may also cause the symptoms to persist. Therefore, patients are advised to avoid the above-mentioned bad habits to prevent symptoms from worsening or continuing to be delayed, and to seek immediate medical attention to clarify the cause of the disease. It should be noted that in addition to improving lifestyle and dietary habits, medications such as ibuprofen and diclofenac sodium can be taken as prescribed by the doctor to relieve pain.
