Symptoms of Inflammation after an Injection

The following symptoms may occur at the injection site:

1. Swelling
2. Itching
3. Pain
4. Redness
5. Warmth
6. Drainage at the injection site
7. Rash

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:

1. Packs of ice. This aids in the reduction of swelling, itchiness, and pain.
2. Pain relievers sold over the counter. This aids in the reduction of pain and inflammation.
3. 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.
