Can a Tight Hamstring Cause Knee Pain?

One of the trickiest things about knee pain is that it’s difficult to pinpoint the cause. Knee pain can be caused by injury, underlying medical conditions like arthritis, too much repetitive use, and many other factors. Even your muscles can be the culprit - did you know that a tight hamstring and knee pain are related?

In this article, we will look at the relationship between a tight hamstring and knee pain, and answer the question “can a tight hamstring cause knee pain?”. We will also offer up some helpful fixes and tips for relieving tight hamstrings and knee pain.

Can a Tight Hamstring Cause Knee Pain?

A tight hamstring causing knee pain is actually pretty common, particularly in runners, weightlifters, and other groups of people who regularly experience tight hamstrings. Often, hamstring tightness results in knee pain when bending or straightening the knee. 

Not only does a tight hamstring cause knee pain, but other muscle groups can also be to blame. Tight calves & knee pain often go hand in hand, and tight quadriceps are another common cause of knee pain. Often, if a muscle group is causing your knee pain, you might also be experiencing stiffness and reduced flexibility. 

Why Does a Tight Hamstring Cause Knee Pain?

Now that we’ve answered the question “does a tight hamstring cause knee pain,” let's look at the relationship between a tight hamstring and knee pain. While your hamstrings and your knees might not seem like they have a lot in common, they actually have to work very closely together, especially during exercise. Your hamstring muscles run from the hip to the back of your knee. When they are tight, they can put an additional strain on the knee joint, which can cause pain and discomfort in your knee. 

Your hamstrings can also cause knee pain if they are tight during exercise. For example, if you are doing squats, and your hamstrings are too tight for you to fully extend your hips, your quadriceps will take charge and put a lot of extra strain on your knees. Not only can a tight hamstring cause knee pain, but it can also increase your chances of injury, so it’s something you should take care of as soon as you can.

So, how do you deal with a tight hamstring causing knee pain? Let’s look at some of the most effective ways of treating tight hamstrings and reducing your knee pain. 


There are so many benefits of stretching. Stretching before a workout reduces your risk of injury and prepares your muscles for exercise. Stretching when you wake up relieves stress and tension, improves flexibility, and gets your body ready for the day. And of course, stretching is an amazing solution for a tight hamstring and knee pain because it improves your flexibility.

So, how long does it take to get flexible? With the right stretching equipment, you can increase your flexibility in a matter of weeks.

Perfect for hamstring tightness, you can use the CastleFlexx to stretch out your hamstrings by lying on the floor, putting your heel inside the hole of the CastleFlexx, raising your leg until it’s straight, and pulling back very gently on the handle of the CastleFlexx. Regular stretching can help loosen your hamstring muscles and prevent a tight hamstring causing knee pain. 

Deep Tissue Work (Foam Rolling, Massage, and More)

Deep tissue work refers to a specific type of massage therapy that really gets deep into your muscles. Firm pressure and slow strokes are applied to problem areas, to target deeper layers of connective tissue and muscle. This is a really effective way of breaking up muscle knots, and loosening tight hamstrings. 

If you don’t want to invest in a massage, you can also do deep-tissue work yourself with a foam roller. If you need to know how to fix a tight hamstring, sit on the floor with your legs outstretched, and place a foam roller under your hamstring. Gently shift your body weight back and forth so that the roller moves from your glutes to your knee. Roll each leg for 30-60 seconds. 

Cold/Heat Therapy

Cold and heat therapy can both be used to combat a tight hamstring causing knee pain. Usually, cold therapy is used for acute injuries, like a hamstring strain, but it might also be helpful for general hamstring tightness. Heat therapy is usually used to relax muscles and reduce stiffness. You can try both heat and cold therapy to see what works best for your hamstring. 

Strengthen Other Muscle Groups

Not only does a tight hamstring cause knee pain, but it can also affect your other muscles, causing them to overcompensate when your hamstrings are not working at full capabilities. This is where strengthening exercises come into play. You can use strengthening exercises for the muscles around your hamstrings, like your glutes, hips, and lower back. 

You can strengthen your glutes with squats and lunges, and try some stretches for tight glutes as well. For your hips, knee lifts and leg raises are excellent strengthening exercises, and for your lower back, try some glute bridges, planks, and abdominal crunches. 

Give Your Body Time to Rest

As frustrating as it can be, sometimes there isn’t anything you can do except rest to heal a tight hamstring and knee pain. If your tight hamstrings are from exercise, the tightness should only last a day or two, and your knee pain should ease as well. Rest is also important when you have muscle pain or tightness so that you don’t accidentally injure yourself further by trying to ignore the pain and muscle tightness.
