ThermaCare Advanced Back Pain (L-XL Size) and Neck Pain Combo Pack {Product Review} The ThermaCare Advanced Back Pain (L-XL Size) and Neck Pain Combo Pack is a great product for anyone who suffers from back or neck pain. The pack comes with 8 back wraps and 1 neck wrap, which can be used up to 16 hours of pain relief. This makes it perfect for those who work long hours at their desk or have busy schedules. One thing that sets this product apart is its ability to target specific areas of the body. The back wraps are designed to provide targeted relief to the lower back and hips, while the neck wrap can be used on the neck, wrist, and shoulder. This makes it a versatile product that can be used by anyone who needs pain relief in those areas. Another great feature is that this product is made with natural ingredients that are safe for use. It's also paraben-free, which means you don't have to worry about harmful chemicals being absorbed into your skin. Additionally, it's made in the USA, so you know you're getting a high-quality product that has been manufactured to strict standards. Overall, I would highly recommend this product to anyone who suffers from back or neck pain. It's easy to use, effective, and safe for use.
