When to use ice or heat for pain? ✅ Use ice for acute injuries (like sprains or strains) within the first 24-72 hours to reduce pain and swelling by constricting blood vessels. Use heat for chronic pain, muscle stiffness, and to increase blood flow to promote healing after the initial swelling has gone down, as it helps relax muscles and joints. #IceTherapy #heating #icing #physicaltherapy #paintreatment #inflammation #physicaltherapy #trendingreelsvideo Doc Jun | Jun Reyes
