Introduction
Whether to use cold or heat therapy for knee pain caused by excessive exercise should be determined based on the timing of the pain. For acute injuries or sudden worsening of pain, cold therapy is recommended within the first 72 hours, as directed by a healthcare provider. For chronic pain or acute injuries that have subsided after 72 hours, heat therapy may be applied under medical guidance. Additionally, each session should not exceed 30 minutes to avoid skin damage.
In general, whether to use cold or heat therapy for knee pain caused by excessive exercise should be determined based on the timing of the pain and under a doctor's guidance. Specific recommendations are as follows:
1. Cold Therapy
If the injury is acute or the pain has recently worsened, cold therapy is recommended within the first 72 hours. Following medical advice, apply an ice pack or a wet towel to the affected area. This helps constrict blood vessels, reduce inflammation, and effectively relieve symptoms such as pain and swelling.
2. Heat Therapy
For chronic pain occurring more than 72 hours after the injury, or for acute injuries in which inflammation has already subsided, heat therapy may be recommended under medical supervision. Heat application helps dilate blood vessels, improve circulation, and relieve muscle tension, pain, and stiffness.
In addition, when applying either heat or cold therapy, sessions should not exceed 30 minutes to avoid skin damage.
