Muscle strain is generally a trauma caused by improper exercise or sports injury, while lactic acid accumulation refers to the condition in which large amounts of lactic acid build up in the muscles. Patients can undergo three courses of local CT examination. Additionally, lactic acid accumulation can cause localized muscle soreness; thus, it is appropriate to elevate the injured limb and take some pain relievers.
