Everyone knows that cardio is great for getting in shape and building lean muscle, but running long distance can *definitely* wreak havoc on your body. So before you sign up for a Harry Potter-themed running club or start pounding the treadmill at your local gym, it鈥檚 best to know the warning signs of overexerting yourself before you end up with a permanent injury. That鈥檚 why we chatted with Dr. Henry Goitz, MD, academic chief of sports medicine in the Department of Orthopedic Surgery at Detroit Medical Center Detroit Receiving Hospital, to learn all about typical running injuries and how we can best treat them at home. Just remember that if your pain persists, you should contact your physician as soon as possible.

1. Runner鈥檚 Knee (AKA Patellofemoral Pain Syndrome): Patellofemoral pain syndrome (say that five times fast!) is the technical term for pain in your knees while running. 鈥淭here are several conditions about the kneecap [where] runners will experience symptoms,鈥 says Dr. Goitz. 鈥淭he most common is at the bottom of the kneecap called patellar tendonitis, or jumper鈥檚 knee. In this condition, the patellar tendon at the bottom of the kneecap has been overloaded, inflamed, and is causing pain. Other conditions include chondromalacia patella, in which articular cartilage on the underside of the kneecap has begun to break down.鈥

How to Treat It: If you鈥檙e experiencing knee pain, the best thing you can do is strengthen your thigh muscles, suggests Dr. Goitz. 鈥淲ith strong quads and thighs, each step that the runner takes gets distributed to the surrounding muscles as opposed to the kneecap itself, much like how the shock absorber on a car would distribute and dampen impulses from going over bumps.鈥 While daily exercises can help, Dr. Goitz advises speaking with your local physician if your pain worsens to the point where it hurts to walk.

2. Achilles Tendinitis: Unfortunately, even us non-Greek gods can have problems with our Achilles. 鈥淎chilles tendinitis is the overload of the tendon at the bottom of the calf muscle at the insertion near the heel bone,鈥 notes Dr. Goitz. It鈥檚 actually a fairly common injury for runners and athletes of all sorts.

How to Treat It: It鈥檚 time to start stretching, lady. 鈥淲hen the symptoms are so significant in which it鈥檚 both difficult to walk and run, I strongly recommend one seeks medical advice,鈥 says Dr. Goitz. 鈥淗owever, some of the other tricks for improving symptoms before seeing a physician might be to put a heel lift in one鈥檚 sneakers, or find shoes that have extra thickness at the back to support the heel and reduce load during heel-toe push-off while running.鈥

3. Hamstring Issues: One of the most common injuries that runners suffer from is a hamstring pull or strain. 鈥淭hose who experience hamstring strains will, most of the time, have pain either near the buttock area up toward the pelvis, or down toward the knee area,鈥 notes Dr. Goitz.

How to Treat It: According to Dr. Goitz, there鈥檚 a number of things you can do at home to treat hamstring issues. Along with adequate stretching, increased strengthening of the thigh muscles, and proper warm-ups and cool-downs, try regularly using foam rolling exercises too. But if the pain persists, you should definitely get in touch with your doc, advises Dr. Goitz.

4. Plantar Fasciitis: Plantar fasciitis is one of the most common causes of heel pain. It鈥檚 super common in runners and, according to Dr. Goitz, can 鈥渂e precipitated by a worn-out sneaker or existing tightness within the plantar fascia (which is the connective tissue that runs from the heel to the toes).鈥

How to Treat It: The at-home treatment for plantar fasciitis is to stretch the plantar fascia regularly, according to Dr. Goitz. 鈥淭he way to do that is to take your toes and gently bend them back toward you. A folded towel wrapped around your toes like an exercise strap can be just as effective. Regular icing, stretching, and a cushioned heel could also improve some of the symptoms of plantar fasciitis.鈥

5. Shin Splints: 鈥淪hin splints can be very debilitating to a runner. This is essentially inflammation of the tissue surrounding the shinbone (tibia) caused by 鈥榖one overload.鈥欌 But before you visit your GP, you should know: 鈥淪hin splints can oftentimes be misdiagnosed due to the difficulty in distinguishing what constitutes shin splints versus stress fractures of the tibia.鈥 Do your research and don鈥檛 be afraid to ask questions!

How to Treat It: Good news, ladies! 鈥淪hin splints can be very well managed with toe raises, ice, exercise strap pushes and pulls, stretching and massage.鈥 However, if the pain persists to the point where you can鈥檛 exercise anymore, it鈥檚 VERY important that you consult a physician. 鈥淭his is the one condition of the six discussed whereby it鈥檚 very important for the physician to distinguish between typical shin splints or the much more serious stress fractures,鈥 notes Dr. Goitz. 鈥淎 stress fracture that persists can be quite debilitating and can force one from running for several months until healed.鈥

6. Iliotibial Band Syndrome (ITBS): 鈥淚liotibial band syndrome occurs when the ligament extending all the way from the pelvic bone to the top of the tibia becomes very tight and inflamed,鈥 says Dr. Goitz.

How to Treat It: Stretching, stretching, and more stretching. 鈥淚f not properly stretched and strengthened, irritation and inflammation can become more and more severe,鈥 says Dr. Goitz. 鈥淚t鈥檚 very important when experiencing pain on the lateral side (outside) of the knee to consider regular stretching, which will improve the ability to mitigate symptoms while maintaining an active lifestyle.鈥
