Shin splints (medial tibial stress syndrome) is an overload of the inside of the shin: the periosteum and muscle attachments along the lower two thirds of the shin bone become irritated and tender, first only at the start of a run, then throughout the run and eventually even when walking. It is one of the most common running injuries and almost always comes from too much, too soon: more kilometres, harder surfaces, new shoes or more jumping than the tissue has had time to adapt to. It heals with reduced load, stronger calves and feet and a gradual return, but it takes weeks to months. Here is how to tell shin splints from a stress fracture, what helps, how to train your way back and how cupping the calves and lower legs gets the stiff muscles that pull on the periosteum to let go.
What are shin splints?
The shin bone is surrounded by a membrane, the periosteum, and along its inside attach the deep calf muscles (including soleus and tibialis posterior) that control the arch of the foot with every step. When the steps become many and hard and the muscles are stiff or weak, the attachments pull on the periosteum more than it can tolerate, and the bone reacts with pain and sometimes slight swelling along a longer stretch, often a hand's width or more, on the inside of the shin. Typically: diffuse tenderness along the inside of the lower leg, worst when the session starts and afterwards, better once warmed up. Risk factors are a rapid increase in running volume, hard surfaces, worn-out or new shoes, hill running, a pronating foot, stiff calves, weak hip and foot muscles, women with low bone density and beginners who train often.
A stress fracture of the shin is the next step on the same scale and must be ruled out: the pain then sits at a small, specific point that is tender when you press with a finger, hurts throughout the session and often also at rest and at night, and does not improve with warming up. Compartment syndrome instead gives tight, hard lower legs with numbness or weakness in the foot after a while of running, which eases at rest. Both need medical assessment.
When to see a doctor
See a doctor if the pain sits at one point on the shin that is tender to pressure, if it hurts at rest or at night, if you have swelling, warmth or redness over the bone, if the lower leg becomes hard and tight with numbness or weakness in the foot during training, if the pain came suddenly with a jump or fall, if you have a fever, or if you are not better after four to six weeks of reduced load. Women with irregular or absent periods combined with bone pain should mention it to their doctor; low energy availability increases the risk of stress fractures.
Self-care that heals
- Reduce the load, but do not stop training. Cut running back to a level that does not cause pain above 2–3 on a ten-point scale and is not worse the next day. Often that means halved volume, no hills, no intervals, soft surfaces. Keep your fitness with cycling, swimming, aqua jogging or a cross-trainer.
- Ice after training for 10–15 minutes in the first weeks if it relieves. Heat before training and in the evening for the muscles.
- Strengthen the calves and feet. Heel raises on a step with straight and bent knee (for soleus), three sets of 15, every other day; towel scrunches with the toes; single-leg standing. Strong calves and arches are what offload the periosteum in the long run.
- Strengthen the hips. Weak gluteal muscles let the knee and foot fall inwards with every step. Side-lying leg raises, hip bridges, single-leg squats.
- Mobility. Stretch the calf against a wall with straight and bent knee, 30 seconds, three times daily. Roll the calf on a ball or roller.
- Shoes and stride. Replace worn-out shoes (often after 600–800 km), try shoes with more support or cushioning, consider insoles if the foot pronates a lot. Shorter, quicker steps (higher cadence) reduce the load on the lower leg.
- Return step by step. When you can walk and hop on one leg without pain: start with walk–run intervals, increase by at most 10 percent per week, put rest days between sessions, and add hills and speed last. Expect four to eight weeks back to normal training, longer if you have had the problem for a long time.
Cupping the calves and lower legs, step by step
Cupping does not affect the periosteum directly, but the stiff calf muscles that pull on it let go noticeably with light, dynamic cupping, and circulation in the lower leg increases. Many runners use it as recovery after sessions during the return. You need the dynamic mini cup, ideally static cups, and body oil. The ground rule: work on the muscles, not on the tender edge of the shin bone.
- Warm up with a warm shower or ten minutes of easy cycling.
- The calf. Oil. Sit with the leg stretched out or lie on your stomach. Glide the mini cup in slow strokes from the heel up towards the back of the knee, inside, middle and outside, five to eight strokes per line, with light suction. Release before the back of the knee.
- The deep inside of the calf. This is where the muscles that pull on the periosteum attach. Short strokes just behind the inner edge of the shin bone, from the ankle upwards, light suction. Not on the bone edge itself where it is tender.
- Outside of the shin. Strokes along the muscle outside the shin bone (tibialis anterior) from the ankle up towards the knee. It often gets stiff when you change your stride.
- Static. One to two static cups with light suction on the most tender points of the calf, two to three minutes.
- Finish with a calf stretch and a few heel raises.
Two to three times a week, ideally the evening after training. The basics of cupping are in Cupping at home. If the problem goes together with heel pain, read Heel spur and plantar fasciitis, and with knee pain Runner's knee. For recovery between sessions: Muscle soreness and Foam roller or cupping?
When not to cup
Not directly on the tender edge of the shin bone or on a point-tender spot (suspected stress fracture), not on a swollen, warm or red lower leg, not with suspected compartment syndrome or blood clot (one-sided swollen, warm, tender calf), not on varicose veins, wounds or bruises, and not without medical advice if you take blood thinners or are pregnant. If the pain increases with cupping, stop.
Frequently asked questions
How long do shin splints take to heal?
With reduced load and strength training it usually takes four to eight weeks to get back to normal running. If you keep running as usual through the pain it can take months and at worst develop into a stress fracture.
Can I run with shin splints?
Often at reduced volume, on soft surfaces and without hills, if the pain is low and not worse the next day. If it hurts throughout the session or at rest: stop running until you have been assessed.
Does cupping help with shin splints?
Cupping the calf and lower leg muscles can reduce tension in the muscles that pull on the periosteum and increase circulation, which many find relieving. What heals is reduced load, stronger calves and feet and a gradual return.
How do I know if it is a stress fracture?
Pain at a small, specific point that is tender when you press with a finger, that hurts at rest and at night and does not improve with warming up. Then stop running and see a doctor; an X-ray or MRI gives the answer.
Do I need insoles or new shoes?
Worn-out shoes should be replaced, and shoes with more support can help if the foot pronates a lot. Insoles help some people, but strong feet and calves and a sensible training progression do more than any shoe.
