Abdominal muscle soreness is mainly due to the normal reaction caused after a long time of strenuous abdominal activities, such as flat support, sit-ups, etc.. First of all, after exercise can be flat rest, and appropriate elevation of the lower limbs and the same level of the heart, conducive to the relaxation of the abdominal muscles to promote venous reflux. Secondly, you can properly carry out local hot compresses and massage, which is conducive to promoting local blood circulation and promoting the metabolism of lactic acid to reduce the symptoms of soreness. Finally, if the abdominal muscle soreness is particularly severe after exercise and lasts for a long time, consider the possibility of abdominal muscle strain due to improper exercise. It is necessary to give local heat compress after 24 hours, apply diclofenac diethylamine latex locally, and can be combined with physical therapy such as acupuncture and infrared radiation. Pay attention to rest and temporarily reduce abdominal exercise to promote the repair of muscle tissue.
