Lateral thigh pain may be caused by physiological factors such as excessive activity, or by pathologic factors such as local soft tissue injury and fasciitis. 1. Physiological factors: due to the high intensity of aerobic exercise will produce a large amount of lactic acid, due to the lack of oxygen supply leads to lactic acid can not be broken down in a timely manner, thus piling up in the muscle, and ultimately lead to the patient’s thigh soreness and pain when pressing the phenomenon. Generally, it can be gradually relieved with proper rest. 2. Local soft tissue injury: when the local soft tissue of the outer thigh is injured, bruising, swelling and pain will occur locally, resulting in pain when pressing on the outer thigh. 3. Fasciitis: when the patient’s leg repeats a certain action for a long time, it is easy to form local aseptic inflammation, thus forming fasciitis. When the affected area is pressed, dispersed pain may appear, and the pain will be aggravated after being cold or overworked, resulting in lateral thigh pain when pressed. When the patient has lateral thigh pressure pain and the symptoms continue to be unrelieved, it is recommended to consult a doctor in a timely manner and standardize the treatment under the guidance of the doctor.
