Hyaluronic acid lump


Hello, I have a hard lump the size of a one-dollar coin near the junction of my chin and neck.
It looks normal, is very firm, but does not hurt.
I had hyaluronic acid injections nine months ago.
Could this be related to that? Thank you.

Hello! Thank you for your question regarding the hard lump you have noticed after receiving hyaluronic acid (HA) injections. It's understandable to be concerned about any changes in your body, especially after cosmetic procedures.

Hyaluronic acid is a substance that is naturally found in the body, particularly in connective tissues, skin, and cartilage. It is commonly used in aesthetic medicine for facial fillers, as it can add volume and hydration to the skin. However, like any medical procedure, HA injections can have side effects, including the formation of lumps or nodules.

The hard lump you are experiencing could be a few things:
1. Localized Reaction: After HA injections, it is not uncommon for patients to experience localized reactions. These can include swelling, tenderness, or the formation of hard lumps. These reactions are usually temporary and resolve on their own over time.

2. Granuloma Formation: In some cases, the body may react to the injected HA by forming a granuloma, which is a small area of inflammation. Granulomas can feel firm and may not be painful. They can occur weeks to months after the injection.

3. Product Migration: Sometimes, the HA filler can migrate from the original injection site, leading to lumps in areas that were not treated. This can happen due to movement, pressure, or the natural dynamics of the facial tissues.

4. Infection: Although less common, an infection can occur at the injection site, leading to swelling and firmness. This would typically be accompanied by other symptoms such as redness, warmth, and pain.

5. Hyaluronic Acid Persistence: HA fillers can last for several months, and in some cases, the product may not fully integrate into the surrounding tissue, leading to palpable lumps.

Given that your lump is hard but not painful and has been present for nine months, it is likely a localized reaction or a granuloma. However, it is essential to consult with a qualified healthcare provider or a dermatologist who specializes in cosmetic procedures. They can perform a physical examination and may recommend imaging studies or a biopsy if necessary to rule out other causes.

In terms of management, if the lump is not causing any discomfort or functional issues, it may not require any treatment. However, if it is bothersome or if you have concerns about its appearance, your healthcare provider may suggest options such as:
- Observation: If the lump is stable and not causing any issues, monitoring it over time may be sufficient.

- Injection of Steroids: In some cases, corticosteroid injections can help reduce inflammation and soften the lump.

- Surgical Removal: If the lump persists and is bothersome, surgical excision may be considered.

As for your question about the timing of treatment, it is best to address any concerns as soon as they arise. Early intervention can often lead to better outcomes.

In conclusion, while the hard lump you are experiencing could be related to your previous HA injections, it is crucial to have it evaluated by a professional to determine the exact cause and appropriate management. Thank you for your inquiry, and I hope this information helps you understand your situation better!
