Persistent Hard Lumps After Injections: What Should You Do? - Surgery

More Info

---

Persistent hard lumps after injections can be concerning, especially when they last for an extended period, such as 10 months in your case. It's important to understand that while some localized reactions to injections, such as swelling or hard lumps, can occur, they should typically resolve within a few weeks. The fact that you still have lumps that are approximately 2 centimeters in size suggests that further evaluation is warranted.

When injections are administered, especially in the gluteal region, there can be several reasons for the formation of hard lumps. These can include:
1. Local Reaction: The body may react to the injected substance, leading to localized inflammation. This can cause the formation of a lump as the body attempts to heal the area.

2. Hematoma: If there was any bleeding under the skin during the injection, it could lead to a hematoma, which is a localized collection of blood outside of blood vessels. Hematomas can feel firm and may take time to resolve.

3. Scar Tissue Formation: Repeated injections or trauma to the area can lead to scar tissue formation, which may present as a hard lump.

4. Infection: Although less common, an infection at the injection site can lead to swelling and the formation of a lump. This is usually accompanied by other symptoms such as redness, warmth, and pain.

5. Lipoma: In some cases, what feels like a lump could be a benign fatty tumor known as a lipoma, which is generally harmless but can be removed if desired.

Given that your lumps have persisted for 10 months, it is advisable to consult a healthcare professional. You should consider seeing a primary care physician or a specialist in dermatology or general surgery. They can perform a physical examination and may recommend imaging studies, such as an ultrasound, to better understand the nature of the lumps.

During your visit, be prepared to discuss the following:
- The exact location and size of the lumps.

- Any associated symptoms, such as pain, tenderness, or changes in the skin over the lumps.

- Your medical history, including any previous injections and reactions.

- Any other treatments or medications you have received since the injections.

In some cases, if the lumps are determined to be benign and not causing any issues, your doctor may recommend a watchful waiting approach. However, if there are signs of infection or if the lumps are causing discomfort or concern, further intervention may be necessary.

In summary, while some localized reactions to injections can be normal, persistent hard lumps warrant further evaluation. Consulting with a healthcare professional will help determine the appropriate course of action and ensure that any underlying issues are addressed.
