To speed the healing, you can: 1  Rest the leg. Avoid putting weight on the leg as best you can. 2  Ice your leg to reduce pain and swelling. Do it for 20-30 minutes every three to four hours for two to three days, or until the pain is gone. 3  Compress your leg. Use an elastic bandage around the leg to keep down swelling.
Menstrual cramps are caused by uterine contractions (when the muscles in the uterus tighten and relax allowing blood to leave the uterus). The lining of the uterus releases special chemicals called âprostaglandins.â These substances can increase the strength of the contractions, especially if the levels rise.
During your menstrual period, your uterus contracts to help expel its lining. Hormone-like substances (prostaglandins) involved in pain and inflammation trigger the uterine muscle contractions. Higher levels of prostaglandins are associated with more-severe menstrual cramps.
