If your lower right leg hurts after running, you might be suffering from shin splints, a common running injury. Shin splints is inflammation of muscles, tendons and tissue in the lower leg. The tibia bone -- large bone in the lower leg -- itself may also be involved. Shin splints cause pain along or behind the tibia. This pain often occurs after running or possibly the next day.
Shin splints are especially common in beginning runners who may be training too much too soon or who may have foot placement errors. According to the Sports Injury Clinic, common causes of shin splints in runners are overpronation, or excessive turning inward of the foot during the running stride; oversupination, or excessive rolling outward; inadequate shoes; running too much too soon; running on hard surfaces; and minimal flexibility at the ankle joint.
Pain in your lower leg from shin splints can be mild to severe. The most important thing to speed up the healing process is to rest your leg. Runner's Rescue recommends complete rest for at least five days or longer if you still feel pain. Apply ice packs on your lower leg for 15 minutes at a time and elevate your leg to decrease swelling. Wrap your leg with a compression bandage ad wear new running shoes, sports orthotics and insoles to help the healing process. If self-treatment doesn't ease your pain, see a doctor.
When you are used to running or feel good because you have just started a new running regimen, you can become depressed being inactive with an injury and afraid you won't maintain your fitness level. According to Runners Rescue, pool running is a great way to stay fit and help the shin splint healing process. Pool running allows you to run in a safe environment with your injury supported by the water so you should be able to run with minimal to no pain. If you feel down about not being able to run as usual for a few days, pool running is a great way to still stay fit while recovering.
To prevent a running injury like shin splints from happening in the first place, determine the cause of the injury. Orthotics or insoles might be useful for overpronation or oversupination. The Sports Injury Clinic recommends not increasing your running distance by more than 10 percent a week so your muscles are not overworked. Vary your running surfaces by occasionally running on softer, grassy areas for better shock absorption, and stretch and warm your muscles before running so you don't have tight lower leg muscles.
