Forefoot swelling with calf swelling may be caused by muscle strain, trauma, lumbar disc herniation, varicose veins in the lower limbs and other factors. 1. Muscle strain: recent long hours of strenuous exercise such as running, jumping, hiking, etc., will lead to the body to produce a large amount of lactic acid accumulation in the local muscles, thus causing forefoot swelling with calf swelling. In order to alleviate the symptoms, you need to pay attention to rest, but also in the local hot compresses, magnetic therapy and other treatments. 2. Traumatic injury: local extrusion injury, traffic accident injury, smashing injury, can cause soft tissue congestion, edema, resulting in local swelling, pain, activity restriction, resulting in forefoot swelling with calf swelling. 3. Lumbar disc herniation: when there is lumbar disc herniation, the protruding nucleus pulposus will compress the spinal cord nerve roots, resulting in edema and degeneration of the spinal cord nerves, which leads to the sensation of swollen forefoot with swollen calf. 4. Varicose veins of the lower limbs: standing for a long time will cause poor venous return, resulting in varicose veins of the lower limbs, causing forefoot swelling with calf swelling. If the symptoms persist, it is recommended to consult a doctor for a clear diagnosis and follow the doctor’s instructions for treatment.
