Acute strains, mostly due to inadequate activity, insufficient preparation before the activity, muscle physiology does not reach the state required for strenuous activity, acute muscle injury, commonly in the weaker, less trained people, these people have poor muscle stretch and strength, prone to muscle fatigue or overload, when participating in sports, prone to acute muscle Strain. Once there is an acute strain, we have to follow the following treatment principles: first, to let the muscle fully rest, for example, lower limb muscle strain, we can use the lower limb cast or brace brake, so that the lower limb muscle fully rest, so that the muscle can have time to self-repair, second, within 24 hours can be iced, especially for the more serious parts of the soft tissue injury, there is subcutaneous bleeding parts of the Ice packs can make the capillaries contract to reduce bleeding. Third, the affected limb can be elevated, which is conducive to lower limb venous reflux, reduce soft tissue edema, and the symptoms of swelling and pain. Fourth, you can apply blood-activating and pain-relieving drugs, such as anti-inflammatory and analgesic drugs, such as celecoxib capsules and etoricoxib tablets. Fifth, you can also apply topical analgesic drugs, such as Furtalin ointment, Flurbiprofen Babu cream, these creams can play the role of symptomatic treatment. Sixth, you can use the elastic bandage, the soft tissue injury parts of the pressure bandage, elastic bandage pressure bandage to moderate, not too tight, nor too loose. Moderate pressure bandage on the one hand can promote venous reflux, reduce soft tissue swelling, on the other hand, can reduce capillary bleeding, can also play a protective role on the injury site.
