I have swollen, tight feeling, calf muscle. how can i alleviate this pain?

Could be a spasthism: Muscle spasm as well as possible varicose vein are alleviated by taking anti-inflammatory medications and possibly using a warm moist wrap for 1-2 hours at a time. However, the best option for unremitting pain and swelling is to see your physician to rule out a blood clot in your deep leg veins/ dvt, as it could be a serious issue.
