Back fascia strains are usually caused by carrying heavy objects or lifting heavy objects. The main symptom is pain and discomfort in the area of the back, which is especially aggravated by localized exertion. Acute strains are more severe and may interfere with normal sleep. If the strain is more serious, the local area may have a slight swelling, and at the same time there is obvious pressure pain when pressing the local area. Back pain can be induced when bending or getting up and turning over to change positions. For back fascial strain, local medication and physical therapy are usually the mainstay, and etofenamate gel can be applied locally for pain relief. Temporarily need to rest, avoid heavy physical labor as well as lifting heavy objects, can also spray swelling pain aerosol to activate blood circulation and remove blood stasis. For not serious back fascial strains, after resting and treatment for 3-5 days can usually improve significantly.
