Calf swelling and tightness may be due to physiological reasons, but also due to pathological reasons such as lower extremity venous embolism, myofasciitis, renal dysfunction, cardiac function injury.
1. Physiological reasons: over-exercise, over-exertion, cold calves and other physiological reasons can lead to calf swelling and tightness, which can be relieved after resting and keeping warm.
2. Pathological causes
(1) Lower extremity venous embolism: Due to venous embolism in the blood vessels of the lower extremities, blood circulation is impaired, resulting in local ischemia and hypoxia, which will lead to swelling and tightness of the calves.
(2) Myofasciitis: Aseptic inflammation of calf muscles and fascia due to trauma, cold, etc. can cause symptoms such as swelling and pain and muscle tightness in the calf.
(3) Renal dysfunction: due to suffering from nephritis or nephropathy, the glomerular filtration rate decreases and too much water accumulates in the body, resulting in edema and tightness in the calves.
(4) Heart function damage: the occurrence of cardiac arrhythmia, heart failure, etc., will reduce the effective circulating blood volume of the whole body, which in turn affects the metabolic function, and there is excessive accumulation of lactic acid in the calves, so it will lead to swelling and tightness in the calves.
There are many other causes of calf swelling and tightness, such as infection, trauma, osteofascial compartment syndrome, etc. If it is not relieved by rest or warmth, it is recommended to consult a doctor in time, complete the relevant examinations, and follow the doctor’s instructions for targeted treatment after clarifying the cause of the disease, so as not to delay the condition.
