What is the usual duration of redness and swelling after a trapezius (trap) injury?

From the Guidelines

Redness and swelling after a trap injury, such as a sting, can last around 1 week or more, typically peaking at 48 to 72 hours. This is based on the study by 1, which discusses large local reactions to stings.

Key Points to Consider

• The duration of redness and swelling can vary depending on the individual's response to the sting.
• In most cases, the reaction is the result of an IgE-mediated late-phase reaction, as noted in the study by 1.
• While the risk of a systemic reaction is relatively low, it's essential to monitor the affected area for signs of infection or worsening symptoms.

Management and Care

• Apply ice for 15-20 minutes every 2-3 hours during the first day to reduce swelling.
• Switch to warm compresses after 24 hours to promote healing.
• Over-the-counter pain relievers like acetaminophen or ibuprofen can help with pain and inflammation.
• Keep the affected area elevated when possible and avoid putting pressure on it.

When to Seek Medical Attention

• If the redness spreads, becomes streaky, or is accompanied by increasing pain, warmth, pus, fever.
• If symptoms don't improve after 3-4 days, as these could indicate infection. It's crucial to prioritize caution and seek medical attention if there are any concerns about the severity of the reaction or potential complications, as emphasized by the study by 1.

From the Research

Redness and Swelling after Injury

• The duration of redness and swelling after an injury, such as a trap, is not directly addressed in the provided studies 2, 3, 4, 5, 6.
• However, the studies discuss the inflammatory response and its relationship to infection and tissue damage 2, 4, 6.
• The inflammatory response, which includes redness and swelling, is a natural defense mechanism that can be triggered by injury or infection 2.
• The duration of redness and swelling can vary depending on the severity of the injury and the individual's response to inflammation 4.

Factors Affecting Redness and Swelling

• The use of nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen can affect the inflammatory response and potentially reduce redness and swelling 3, 4, 5, 6.
• However, the effectiveness of NSAIDs in relieving symptoms of infection and inflammation can vary depending on the specific condition and individual response 5, 6.
• Other factors, such as comorbidity and length of hospitalization, can also affect the duration and severity of redness and swelling 5.
