Patient's question:
It has been over ten days since I got the hepatitis B vaccine, and I have a feeling of bloating and pain. It hurts when I press it while taking a nap. Is this normal?Doctor's answer:
The hepatitis B vaccine is administered intramuscularly in the deltoid muscle of the upper arm, with one dose per injection. For acute infection, individuals with hepatitis or other serious illnesses or allergies should discontinue use. The injection site may experience redness, swelling, pain, or warmth as side effects. Note: Shake the vaccine thoroughly before use. Do not use if there are undissolved clumps. Generally, there is no interference with daily work and life after receiving the hepatitis B vaccine. To date, no serious adverse reactions following the injection have been reported.
