Q: What's the advantages of the heat cold pad?

A: Heat can increase blood flow and help restore movement to injured tissue. Warmth can also reduce joint stiffness, pain, and muscle spasms. As with cold packs, heat packs have a role in easing pain from both acute and chronic injuries, such as sprains, strains, muscle spasms, whiplash, and arthritis. Doctors often suggest using cold packs for the first day or two, and then switching to heat if the symptoms persist or become more chronic.
