The simple answer is no. When you have been active, muscles are already heated up. More heat may feel good, but cold will help your muscles recover.
If you have a small sore spot, make a homemade ice pack. Fill a paper cup with hot water and then freeze it. Peel down the rim of the paper cup to expose the ice surface. The remaining paper cup will serve as a holder. Gently swirl the ice on the sore area, keeping it moving to prevent frostbite. Initially, it will feel uncomfortable, but a 5 to 10 minute treatment should provide prompt relief.
If the area needing treatment is larger, a bag of frozen peas makes a great pliable ice pack. It can also be refrozen and reused over and over again.
At our clinic, we also offer a variety of professional products for home use that are designed to reduce pain and facilitate muscle recover. Ask us about them during your next visit.
