After the appearance of the pillow must be hot compresses, but not cold compresses. The pillow is due to sleep at night because the pillow is too high or too low, the muscle is not in a relaxed state, muscle tension for a long time leading to fatigue, and even strain. Usually due to the slowing of blood circulation after the cold, the accumulation of inflammatory metabolites, stimulating the surrounding muscles leading to further muscle tension, and there is significant pain. So you can not use cold compresses, if cold compresses will lead to further slowing of blood circulation, more inflammatory metabolites accumulation, more obvious stimulation of the surrounding nerves, and more obvious pain. Therefore, hot compresses should be applied, generally 3-5 times a day, 20-30 minutes each time, the temperature of the hot compress is hot, and can be tolerated, after the hot compress blood circulation accelerated, inflammatory metabolites no longer accumulate, the symptoms will also be significantly improved.
