Injuries within the first 24-72 hours are usually acute and should not be treated with heat to avoid worsening the condition.
Acute injuries are those that are recent or sudden, typically within the first 24-72 hours. Heat is generally not recommended for such injuries as it can increase inflammation and pain.
Using heat on an acute injury can potentially worsen the condition by dilating blood vessels and increasing blood flow, which may lead to more swelling.
It is important to follow the RICE protocol (Rest, Ice, Compression, Elevation) for acute injuries to help reduce pain and inflammation.
