Why Did My Plantar Fasciitis Start After Increasing My Mileage?

Heel or arch pain after increasing your running mileage often starts when your foot begins to feel sore or tight during or after runs because the plantar fascia is handling more repeated stress than it can comfortably recover from.

You may notice plantar fasciitis for the first time after adding extra miles, extending your long run, or suddenly running more days each week. During a run, the bottom of your heel or arch may start to ache, pull, or feel bruised, and the discomfort can become more noticeable as the miles add up.

You may also notice the foot feels stiff when you first get out of bed or after sitting between runs. When your mileage increases faster than your foot can adapt, the plantar fascia keeps getting stressed before it has enough time to settle down, so the same heel or arch pain can return on your next run.

Your Heel Starts Hurting As Miles Add Up

The heel may start aching once your run gets longer than usual.

You might feel fine during the first part of a run, then notice a sore or sharp spot under the heel as the miles accumulate. The longer running time gives the plantar fascia more repeated work, which can make a recent mileage increase show up as pain that was not there before.

Your Arch Feels Tight After More Running

Your arch may feel tight, tender, or pulled after increasing your mileage.

You may notice the arch becoming uncomfortable during a longer run or feeling sore when you walk afterward. If you keep adding miles while the foot is still recovering, the plantar fascia can remain sensitive between runs instead of settling down completely.

Why More Miles Keep Bringing Pain Back

Your foot 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 a cycle of reinjury.

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 foot feeling stiff, tight, weak, or painful during everyday movement and activity.

What Can Help Your Foot Feel Better

Your foot 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 did my plantar fasciitis start after increasing my mileage?

Increasing your running mileage can put more repeated stress on the plantar fascia than your foot has adapted to, leading to new heel or arch pain.

Where does plantar fasciitis hurt after increasing running mileage?

You may feel pain under the heel, through the arch, or along the bottom of the foot, particularly during or after longer runs.

Why does my heel hurt more on longer runs?

Your heel may hurt more as the miles accumulate because the plantar fascia is repeatedly stressed for a longer period than it was used to handling.

Can plantar fasciitis from running get worse if I keep increasing mileage?

Yes. Continuing to increase mileage while the foot remains painful can keep stressing the plantar fascia before it has enough time to recover.

How long does plantar fasciitis take to improve after increasing mileage?

Improvement varies, but reducing the activity that aggravates the pain and allowing the foot time to recover can help prevent repeated flare-ups.
