If an athlete experiences knee pain and notable swelling, which step should be taken first?

When an athlete experiences knee pain and notable swelling, the immediate priority is to alleviate symptoms and prevent further injury. Applying ice and resting the knee is vital for reducing inflammation and managing pain. Ice therapy helps constrict blood vessels, which can decrease swelling and numb the area, providing relief. Rest is essential to avoid exacerbating the injury and allows the body to begin its natural recovery process.

Continuing training can lead to worsening the condition and may cause more significant injury, which counters the goal of rehabilitation. Immediate ultrasound therapy is also not the first line of action for managing acute swelling and pain; it usually comes later in the treatment process as part of rehabilitation. Visiting a nutritionist does not address the immediate physical symptoms the athlete is experiencing. Therefore, applying ice and resting the knee is the most appropriate first step in managing knee pain and swelling.
