Experiencing sudden foot pain without injury can be confusing and frustrating. Many people in Surrey visit our orthopaedic clinic with sharp or persistent foot discomfort that seems to appear out of nowhere. While injuries and overuse are common culprits, there are also several medical reasons why pain might arise unexpectedly.
In this guide, we explore five possible causes of unexplained foot pain and explain when it might be time to seek expert help from a local specialist.
Nerve Entrapment and Tarsal Tunnel Syndrome Causing Sudden Foot Pain
One potential reason for sudden foot pain is nerve entrapment, including a condition known as tarsal tunnel syndrome. This occurs when one of the main nerves in the foot becomes compressed as it travels through a narrow space near the ankle. The result is often a burning or tingling sensation that radiates across the heel, arch, or bottom of the foot.
You may notice that the pain worsens when you’re at rest or lying in bed at night, which can make it difficult to sleep. There may be no visible signs of injury, but the discomfort can become increasingly intrusive. In cases like this, a combination of physical therapy, custom orthotics, or targeted injections may be recommended, and in rare situations, surgical release of the nerve may be needed.
Plantar Fasciitis As A Cause Of Sudden Foot Pain
Although plantar fasciitis is commonly linked to gradual discomfort, it can also cause sharp and sudden pain, particularly in the heel or the bottom of the foot. This often occurs when you first get out of bed in the morning or after long periods of standing still.
The plantar fascia is a thick band of tissue that supports the arch of your foot. If it becomes irritated or inflamed, even subtle changes in your activity levels or footwear can cause it to flare up quickly. Patients frequently look online for how to relieve pain on the bottom of feet, often assuming it’s a minor strain, but a proper diagnosis is crucial for long-term relief.
Stress Fractures and Bone Bruising Causing Sudden Foot Pain
Even if you haven’t experienced a clear injury, it’s still possible to develop a stress fracture or a bone bruise, particularly if you’ve recently increased your walking, running, or gym activity. These tiny cracks in the bone are most common in the metatarsals, heel, or ball of the foot, and can trigger sudden pain when walking or putting weight through the foot.
While you might not notice swelling or bruising at first, the discomfort usually gets worse with activity and improves slightly with rest. Stress fractures require medical imaging to confirm, and early intervention is important to prevent the fracture from worsening.
Tendonitis and Tendon Strain Leading To Sudden Foot Pain
Inflammation of the tendons in your foot can also cause unexplained pain, especially if you’re active or have recently started wearing unsupportive footwear. One of the most common forms is posterior tibial tendonitis, which affects the tendon running along the inside of your ankle and into the arch of the foot.
The pain tends to start subtly but can become more noticeable when climbing stairs, walking for long distances, or standing for extended periods. Morning stiffness or pain along the inside of the foot is common, and the discomfort may reduce slightly once you’ve been moving for a while. Many people mistake this type of pain for a muscular issue or general fatigue, but untreated tendonitis can lead to long-term complications.
Arthritis or Gout Flare-Up Causing A Sudden Foot Pain
In some cases, what feels like sudden foot pain without injury may actually be the result of an arthritis flare-up or an episode of gout. These conditions can strike quickly, particularly overnight, and cause intense pain and swelling even in patients without a formal diagnosis.
Gout typically affects the joint at the base of the big toe, but other forms of arthritis can also cause pain in the arch, heel, or ball of the foot. The area may feel hot, tender to touch, and visibly red or swollen. If this kind of flare-up occurs, medical evaluation is recommended as blood tests and joint scans may be necessary to guide treatment.
When Should I See a Specialist About My Sudden Foot Pain?
If you’re dealing with sudden foot pain that has no clear cause, it’s important to have it assessed early. Many conditions respond well to treatment when diagnosed quickly, but delaying care can lead to longer recovery times or more invasive options later.

Whether you’re experiencing discomfort in your heel, arch, ball of the foot, or across the bottom of the foot, we can help you find the underlying cause and create a personalised treatment plan.
