Steroid Injections for Scar Treatment: Pain and Side Effects - Dermatology

More Info

---

Steroid injections, particularly for the treatment of hypertrophic scars or keloids, are a common practice in dermatology and plastic surgery. These injections, often containing corticosteroids like triamcinolone acetonide (Kenacort), are designed to reduce inflammation and flatten raised scars. However, it is essential to understand both the expected effects and potential side effects associated with this treatment.


Pain and Discomfort After Injection
It is not uncommon to experience some pain or discomfort following a steroid injection. The injection itself can cause localized pain, and the corticosteroid can lead to a temporary inflammatory response in the treated area. This response may manifest as a sharp or throbbing pain, which can last for a few hours to a couple of days. The pain you are experiencing, described as a "sharp pain," is generally considered a normal reaction to the injection. The slight swelling you noted is also a typical response, as the body reacts to the injected substance.


Expected Side Effects
While steroid injections can be effective in treating keloids and hypertrophic scars, they do come with potential side effects. Common side effects include:
1. Pain at the Injection Site: As mentioned, this is a common and usually temporary side effect.

2. Skin Thinning: Prolonged use of steroids can lead to thinning of the skin in the injected area, which may make the skin more susceptible to bruising and tearing.

3. Discoloration: Some patients may notice changes in skin pigmentation at the injection site.

4. Infection: Although rare, there is a risk of infection at the injection site.

5. Tissue Atrophy: Repeated injections can lead to atrophy of the surrounding tissue, which may affect the appearance of the scar.


Frequency of Injections
Your doctor mentioned that you would need another injection in two weeks. This is a common practice, as multiple injections may be necessary to achieve the desired results. The frequency and number of injections depend on the individual’s response to treatment and the characteristics of the scar. It is essential to follow your doctor's recommendations regarding the timing of these injections.


Monitoring for Adverse Reactions
While most side effects are mild and temporary, it is crucial to monitor your symptoms. If you experience severe pain, increased swelling, redness, or any signs of infection (such as pus or fever), you should contact your healthcare provider immediately. Additionally, if the pain persists beyond a few days or worsens, it may warrant further evaluation.


Conclusion
In summary, experiencing pain and slight swelling after a steroid injection for scar treatment is generally a normal response. While there are potential side effects associated with steroid injections, most are manageable and temporary. It is vital to maintain open communication with your healthcare provider about your symptoms and any concerns you may have. They can provide guidance tailored to your specific situation and help ensure that your treatment is both safe and effective. If you have any lingering concerns or if your symptoms worsen, do not hesitate to reach out to your doctor for further advice.
