Cold calf pain may be caused by physiological reasons such as muscle spasm, or by pathological reasons such as lumbar spine disease, fasciitis, rheumatism and rheumatoid disease, and vascular disease of the lower limbs. 1. Muscle spasm: it is common for the cold environment to stimulate the calf leading to contraction and spasm of the calf muscles, which can cause symptoms of calf pain. 2. Lumbar spine disease: commonly caused by lumbar intervertebral disc herniation that compresses the nerve root, and symptoms of calf pain can appear in the cold environment. 3. Fasciitis: commonly seen in long-term calf cold, resulting in aseptic inflammation of the local fascia and other tissues of the patient, may appear in the calf muscle soreness, pain, restricted movement and other symptoms. 4. Rheumatism and rheumatoid diseases: due to rheumatism and rheumatoid diseases involving the knee joint or calf muscles, symptoms such as wandering cold and pain in the calf can occur. 5. Lower limb vascular diseases: such as Raynaud’s disease, the calf is cold, local vasoconstriction, resulting in distal blood supply is insufficient to lead to cold calf pain. Cold calf pain is recommended to consult a doctor in a timely manner, with the help of a doctor to clarify the cause of the disease, and targeted treatment or treatment.
