Advice after your nerve block for surgery
On this page…
The blister raised by the vaccine starts to disappear within a few minutes. A local reaction develops within 2 to 6 weeks, beginning as a small pea-like lump which increases in size over a few weeks to a round area up to 7mm in diameter, with scaling, crusting and, on occasions, bruising. This will heal over a period of time and generally leaves a small scar.
However, please note that a shallow ulcer up to 10mm diameter may develop instead of the above. This reaction heals more slowly and will require several months to heal, leaving a small scar. In the rare case that this does happen, it is advised that you inform the immunisation nurse.
It is not necessary to protect the site from becoming wet during washing or bathing.
DO’S AND DONT’S
- Do not allow your child to have any vaccinations in the same arm for 3 months. Your child can have non-live vaccines in other limbs. Please ask the administering nurse for more information if unsure.
- Do not use plasters (band aids) over the vaccination site. It is essential that air should not be excluded. If absolutely necessary a waterproof dressing may be applied but only for a short time (e.g., 1-2 hours) as it may delay healing.
- Do not allow your child to scratch the site, as they may make the final scar much bigger.
- Do not allow your child to play contact sport (e.g., football) for 24 hours.
- Do go and seek medical advice from any appropriate, available service such as your GP or Walk-in Centre, if you notice any adverse reactions. Only in an emergency attend Accident and Emergency.
