Understanding Inflammation after Injection
Swelling and irritation (inflammation) at the site where the
needle entered the skin can occur after any injection. This is an allergic
reaction to the needle or the medicine injected. It could also be a reaction to
both. It's possible that the reaction will occur right away. It could also
begin several hours after the injection. The reaction is usually not serious
and goes away on its own. Swelling and irritation

Swelling
caused by injections needs to be treated.
The severity of the reaction and the cause of the reaction
will determine the treatment. The majority of inflammation after an injection
is minor. It disappears on its own after a few hours or days. If treatment is
required, it may consist of one or more of the following:
- Packs of ice. This aids in the reduction of swelling, itchiness, and pain.
- Pain relievers sold over the counter. This aids in the reduction of pain and inflammation.
- Medicine prescribed by a doctor. These are used to treat infections.
Post-injection
inflammation may cause complications.
Be on the lookout for a reaction that spans your entire
body. This can result in skin rashes, severe itching, or raised fluid-filled
bumps known as hives. This type of reaction, especially if it affects
breathing, can be dangerous. If you or your child starts to develop symptoms
that are not related to the injection site, contact your healthcare provider
for advice.
When
should you contact your healthcare provider?
If you have any of the following symptoms, contact your
healthcare provider right away:
- Fever of at least 100.4°F (38°C), or as directed
- At the injection site, there is a lot of pain.
