I Can Walk Fine, but Running Makes the Back of My Thigh Hurt

Pain in the back of your thigh that only appears when you start running can happen when your hamstring is tight, strained, or repeatedly stressed in ways walking does not trigger.

Walking and running can feel completely different when the back of your thigh is bothering you. You may feel fine taking normal steps, climbing around the house, or moving through your day, then notice the area suddenly starts pulling or hurting once you pick up the pace and begin running.

The pain may show up during the first few strides, gradually build as you continue, or feel like the hamstring keeps grabbing every time your leg swings through. This often happens when the muscle has been dealing with repeated stress and running asks more from it than walking does.

The Pain Starts When You Pick Up Your Speed

Your thigh may feel completely normal walking, then start pulling or grabbing as soon as your running stride gets longer and faster.

Running makes your hamstring work through a much bigger and quicker range of motion than walking. If the muscle is tight or still sore from previous activity, that faster movement can expose the problem right away, making the back of your thigh hurt even though ordinary walking feels fine.

The Back Of Your Thigh Hurts More As Your Run Continues

You may get through the beginning of your run, then notice the hamstring becoming tighter and more painful the longer you keep going.

Repeated strides can keep stressing the same sore area before it has a chance to loosen up. You might notice the pain starts as mild tightness, then becomes harder to ignore as the muscle keeps working, especially during faster running, hills, or longer distances.

Why Your Hamstring Keeps Hurting During Runs

Your hamstring has a hard time healing when blood flow and circulation are limited.

Tendons, ligaments, and other soft tissues naturally receive less blood supply than many other parts of the body. Because of this, they often take longer to heal after repeated stress or injury, leaving you more vulnerable to lingering pain and repeated irritation.

When circulation through the area remains limited, injured tissues have a harder time receiving the vital oxygen and nutrients they need to repair and heal. This can leave your hamstring feeling stiff, tight, weak, or painful during everyday movement and activity.

What Can Help Your Hamstring Feel Better

Your hamstring starts feeling better when blood flow and circulation improve.

Chinese herbs have been used for centuries to promote healthy blood flow and circulation. Their medicinal properties help break up stagnant blood and fluids that remain trapped around injured tissues, interfering with circulation. As circulation improves, blood flows more freely through the area, allowing those tissues to receive the oxygen and nutrients they need to heal properly.

Topical herbal remedies made with these Chinese herbs can help relieve pain while improving blood flow and circulation to injured tissues. The right product depends on your symptoms and whether you're in the acute or chronic stage of recovery.

If you have pain, swelling, inflammation, or bruising, Acute Sinew Liniment helps relieve these symptoms by increasing circulation and dispersing stagnant blood and fluids around the injured area to speed recovery. During the acute stage of healing, getting circulation moving early allows injured tissues to receive the fresh blood, oxygen, and nutrients they need to repair and heal.

If your injured area is especially swollen, red, or warm to the touch after a recent injury or flare-up, Sinew Herbal Ice is also used to reduce swelling and inflammation while restoring normal circulation so you can quickly regain range of motion. While traditional ice is commonly used to reduce swelling, Sinew Herbal Ice acts as an ice alternative to reduce swelling and inflammation while also dispersing accumulated blood and fluids to speed the healing process.

If you no longer have swelling or inflammation, but still have pain, stiffness, weakness, or sensitivity in cold and damp weather, Chronic Sinew Liniment helps relieve these symptoms by strongly stimulating circulation and increasing blood supply to injured tendons and ligaments to promote their healing. This is especially important because tendons and ligaments naturally receive less blood supply, which is why chronic injuries can take longer to heal.

If you have residual pain and stiffness, or the area becomes more painful in cold weather, Sinew Injury Poultice is also used to significantly stimulate circulation to injured tendons and ligaments to further promote their healing. By strongly increasing circulation, it counteracts the reduced blood flow caused by cold weather that commonly aggravates chronic tendon and ligament injuries.

If you exercise, play sports, or do other strenuous activities, Sinew Sports Massage Oil warms and stimulates muscles for exertion and relieves muscle tightness and soreness after activity. Warming and preparing your muscles before activity can improve flexibility, enhance performance, and reduce the risk of injury.

Frequently Asked Questions

You may also find these commonly asked questions helpful.

Why does the back of my thigh hurt when I run but not walk?

Walking places less demand on your hamstring, while running requires faster and stronger muscle contractions. A tight or irritated hamstring may only become painful once you increase your speed.

Is it okay to run with mild hamstring pain?

If the pain keeps increasing, changes your stride, or makes you hesitate while running, continuing can keep aggravating the area. Reducing the activity that repeatedly triggers the pain may give the hamstring time to recover.

Why does my hamstring feel fine at first and then start hurting?

The repeated motion of running can gradually irritate a sore area. You may feel comfortable at the beginning, then notice tightness or pain building as more strides accumulate.

Can tight hamstrings cause pain only during running?

Yes. A tight hamstring may handle normal walking without trouble but become painful when running requires it to stretch and contract more quickly.

When should back-of-thigh pain be checked by a professional?

Severe pain, sudden weakness, bruising, swelling, or symptoms that continue getting worse should be evaluated by a qualified healthcare professional.
