Hello. Thanks for posting your query. From description , symptoms you have are more suggestive of muscle cramps. These are often caused by muscle fatigue, heat, or dehydration.You can ease muscle cramps by stopping whatever triggered them. Gently stretch or massage your lower leg muscle. Applying heat to tight muscles or cold to tender muscles may ease some symptoms. Proper conditioning and stretching can help prevent problems in the future. I would suggest getting this evaluated by doctor for an accurate diagnosis and appropriate management. I also advice you some lifestyle changes such as: Quitting smoking if you are smoker Adopting a healthier diet Managing weight if you aare overweight Exercising, gradually increasing walking distance over time Wishing you good health....
