In the clinic, frequent soreness in the calf is a relatively common symptom with many causes. Firstly, it is due to the patient’s overworked calf area, strain or catching a cold, or it may be caused by traumatic injury to the soft tissue of the leg muscles, so that the local lactic acid buildup is too much and the phenomenon of soreness occurs. In addition, if the patient suffers from popliteal cyst, due to the compression of the cyst on the tibial nerve or tibial artery, it can also lead to soreness in the calf area. In other cases, the patient has a history of trauma to the calf, which can lead to soreness in the leg after exposure to cold. All in all, it is best to go to the hospital in time after the occurrence of this phenomenon, after the correct diagnosis by the doctor and then give a clear treatment, so as to avoid delay or further aggravation of the condition.
