1. Knee pain
Knee pain, also called runner's knee, can have many causes, such as swelling under the kneecap. Andy Byrne from David Roberts Physiotherapy in Manchester says that knee pain is the most common condition he treats in runners.
What does runner's knee feel like?
During your run, you may develop pain at the front of the knee, around the knee or behind the kneecap. The pain may be dull or it could be sharp and severe.
What should I do about runner's knee?
To help knee pain at home, Andy recommends applying ice to the knee and stretching. Hold ice (try a bag of frozen peas wrapped in a damp tea towel) on the painful area for around 20 minutes a few times a day. Never put ice directly on your skin.
To stretch the area, Andy recommends lying on your side with your bad leg on top. Bend your top leg so that your foot goes back towards your bottom, then hold it there with your hand and keep both knees touching. Hold the stretch for at least 45 seconds, breathing deeply and feeling the stretch in the thigh. Repeat this around six times a day.
If the pain is severe or the knee is swollen, see your GP straight away. If your knee pain is not severe, stop running and get it checked by a GP or physiotherapist if the pain doesn't go away after a week. They can also recommend stretches or exercises to help you recover.
Can I still run with a painful knee?
Don't run if you have pain in your knee. If you still feel pain after a week's rest, see your GP or physiotherapist. How soon you can start running again will depend on the cause of your knee pain and how severe it is. Your GP or physiotherapist can advise you.

2. Achilles pain
The Achilles tendon is the tough, rubbery cord at the back of the ankle that links the muscle to the bone. Regular running can cause wear and tear to the tendon over time.
What does Achilles pain feel like?
You may have pain and swelling at the back of the ankle or heel. The pain may be minor but continuous, or it could be sudden and sharp. It may be worse first thing in the morning.
What should I do about Achilles pain when I run?
To treat Achilles pain at home, Andy recommends applying ice to the area if you can feel a lump there (never put ice directly on your skin). You can also gently massage the area with your fingers.
You could also try using heel wedges in your shoes. Get advice about this from a sports or running shop.
See your GP or a physiotherapist if you have Achilles pain that doesn't disappear after three to four weeks. If you have a sudden, sharp pain, your Achilles tendon may have torn. See your GP straight away if this is the case.
Can I still run with Achilles pain?
A sharp pain will stop you running altogether. Even if the pain is not severe, it's a good idea to rest until the pain goes, and get it checked if it doesn't go away.
3. Shin pain
Shin pain occurs on the front of the leg, below the knee. It's often referred to as shin splints.
What does shin splints feel like?
Runners are often aware of a dull pain in the shin but carry on running. However, this can cause increasing damage to the area, which can lead to a sudden sharp pain that stops you running altogether.
What should I do about shin pain?
Pain can be relieved by applying ice to the area regularly for the first few days (never put ice directly on your skin). See your GP or a physiotherapist if the area is swollen, the pain is severe or it does not improve in two to three weeks.
Can I still run with shin splints?
Shin pain is likely to stop you running altogether. Take a break for two to three weeks before beginning again slowly. See the Health A-Z topic on shin splints for more information.
4. Heel pain
Pain or swelling in the heel or bottom of the foot can occur if you suddenly start doing a lot more running, if you run uphill or if your shoes aren’t supportive enough or are worn out. The medical name for heel pain is plantar fasciitis.
What does runners' heel pain feel like?
Heel pain is often sharp and occurs when you put weight on the heel. It can feel like someone is sticking something sharp in your heel, or as if you're walking on sharp stones.
What should I do about heel pain?
Andy recommends applying ice to the area. He says the best way to do this is to freeze a small bottle of water, then place it on the floor and roll it back and forth under your foot for about 20 minutes. Never place ice directly on your skin.
There are also several stretches you can do to help heel pain. See the Health A-Z section on treating heel pain for guidance on how to do them.
Stop running and see your GP straight away if there is a lot of swelling in the heel or the area under your foot. Otherwise, see your GP after a week to 10 days if the pain doesn’t go away.
Can I still run with a painful heel?
You won’t be able to run with heel pain. If you treat the pain early enough, it will normally go away in two to three weeks, after which you should be able to start running again.
5. Muscle strains
The most common strains due to running are in the hamstring muscles (which run down the back of the thigh) or calf muscles. Strains often affect new runners, whose muscles are not used to running.
What does muscle strain feel like?
The pain of a muscle strain is often sudden and feels as if someone has kicked you in the area of your calf or hamstring.
What should I do about a muscle strain?
Most strains can be treated at home. Stop running immediately and apply ice to the painful area for around 20 minutes a few times a day (don't put ice directly on your skin). Keeping your leg elevated and supported with a pillow will help reduce swelling. Find out more about treating strains.
Can I still run with a muscle strain?
You won't be able to run with a muscle strain. The time it takes for a strain to heal and for you to start running again varies from two weeks to around six months, depending on how severe the muscle strain is.
Tips for preventing injury
Wear the right shoes
It's important to buy the correct running shoes, and it's best to go to a running shop to get fitted. However, you don't have to spend a lot of money.
According to Andy, expensive shoes are not necessarily better. "The most expensive shoes may just be more durable and lightweight, so are suitable for people running long distances. All running shoe brands make cheaper versions that are suitable for beginners."
Warm up and cool down
It's essential to warm up properly before you start running. Five to 10 minutes of brisk walking or gentle jogging before you start will warm your muscles up and help prevent injury. To cool down, carry on running at an easier pace or walk for five to 10 minutes. This will help your body recover after your run. See Tips for new runners for more information about warming up and cooling down, as well as running technique.
Build up slowly
Don't be tempted to increase the intensity or distance of your running too quickly. "Do a similar run at least three or four times before you increase your pace or distance," says Andy.
The Couch to 5K plan is perfect as it builds up the distance gradually. The plan is suitable for beginners and will get you running three times a week, building up to 5km in nine weeks.
Staying motivated if you have an injury
Being injured can be very frustrating. If you’re new to running, you might be tempted to give up at the first sign of injury.
Andy says that having a specific goal, such as a 5km race or charity run, will help you stay motivated through injury. “If you have something to work towards, you'll be much more likely to get back into running once you've recovered.”
Running with a partner is also a great way to stay motivated. If they carry on running while you're injured, you'll want to get back out there once you're better as you won't want to let them down.
