Cervical Spine Pulse Tractor : Are you troubled by cervical spine problems, neck pain, headaches and other problems caused by long hours of work? Our cervical traction device will help relieve neck pain (please note that this device is only for cervical traction and cannot be used as a regular pillow while sleeping). 6 Levels of Adjustable Massage Strength : Set the controller from the side, then apply strength and massage intensity according to your needs. If you need to apply hot compress to massage the cervical spine, you can start with a low temperature of 40 for 15 minutes each time and no more than 30 minutes a day. Your neck will get hot very quickly. There is no charger included in the package. Just plug the Type-C cable into the mobile power supply, PC or USB adapter (5V=2A charger) to select the appropriate temperature and time as needed. Relieve pain anytime, anywhere : Heated neck traction is your good companion no matter at home, in the office, or traveling. Unlike most traditional cervical traction systems, this neck support is easy to use by simply lying comfortably on the couch or bed, or even leaning on a neck stretcher while working at the computer. It weighs 0.9 pounds and has a compact size that makes it easy to carry. Notes: Do not use it as a regular pillow and do not use it for more than 30 minutes or overnight. It usually takes a few days to get used to this pain relief device, as it takes time to adjust to the contours of your neck and become familiar with the curves of your new orthosis. Tip : When you use the neck traction device for the first time, you may find that its material is a bit hard, and you may feel stiffness or even slight pain, which is completely normal for first-time users. Only in this way can the effect of cervical spine pain be produced, which also means that your cervical spine is being corrected. You will feel better after a week of use. Gradually increase the time of use to allow your body to adjust to the pillow. Adjust and get the correct position until comfortable. This is a process, so don't use it too often.
