If your clients are looking for a way to relieve pain from tension headaches, muscle soreness or injury, traditional spa services aren't always the answer. In these cases, hot and cold treatments can be a replacement for or addition to other services available in your practice. From portable hydrocollator heating units for massage therapy to simple cold packs, there are a range of options when it comes to using heated or cold items for pain relief. And though any practice should have a few of these items on hand, some can also be used at home for pain relief in between professional treatments. For example, a neck and shoulder wrap can be a great way for individuals to relieve tension in the area in between massage appointments.
