Why Tingling, Burning, or Numbness in Your Feet Deserves Attention
Have you ever felt a burning, tingling, or numb sensation in your foot and wondered what’s going on? These odd sensations can be unsettling, especially when they come out of nowhere. You might think it’s just “pins and needles” that will go away, but it could be a sign of something more—like a neural entrapment.
What is a Neural Entrapment?
Neural entrapment, also known as nerve compression, occurs when a nerve is compressed or irritated by surrounding tissues, such as bones, muscles, or ligaments. This compression can disrupt the normal function of the nerve, leading to sensations like burning, tingling, or numbness in the affected area. These symptoms are your body’s way of signalling that something isn’t quite right with the nerve’s and the signal is disrupted or blocked.
Common Areas for Neural Entrapments
Neural entrapments can occur in various parts of the foot, but two common areas are the ball of the foot and the heel.
1. Ball of the Foot (Morton’s Neuroma)
One of the most common neural entrapments in the ball of the foot is Morton’s neuroma. This condition involves the thickening of tissue around one of the nerves leading to your toes. It usually occurs between the third and fourth toes and can cause sharp, burning pain, tingling, or numbness. You might feel like you’re standing on a pebble or have a folded sock in your shoe. Morton’s neuroma is often caused by wearing tight or high-heeled shoes, which put pressure on the toes and the ball of the foot, but it can also result from repetitive stress or abnormal foot mechanics.
2. Heel (Tarsal Tunnel Syndrome)
Another common neural entrapment site is the heel, where the tarsal tunnel syndrome occurs. This condition involves the compression of the posterior tibial nerve as it passes through a narrow space inside the ankle called the tarsal tunnel. Symptoms can include a burning sensation, tingling, numbness, or shooting pain in the heel, arch, and even the toes. Tarsal tunnel syndrome can result from flat feet, varicose veins, ankle injuries, or any condition that causes swelling or compression in the tarsal tunnel area.
How Can a Podiatrist Help?
- Assessment: We start with an examination, including a discussion of your symptoms, medical history, and lifestyle. We may in some cases send you for imaging tests like Ultrasounds or MRIs to get a detailed look at the structures in your foot.
- Orthotics: Orthotics can help redistribute pressure, support your arches, and improve your foot mechanics. This can relieve pressure on the nerves and reduce symptoms.
- In Shoe padding: In some cases, we may make padding from a foam material that we place in your shoes to offload specific areas of the foot and help relieve the nerve. If we make orthotics this padding will be incorporated into your orthotics.
- Footwear Advice: We can offer some advice on footwear features to help alleviate pressure on the affected areas. This might include shoes with a wider toe box, better arch support, or cushioning.
- Low Level Laser Therapy (LLLT): LLLT is a non-invasive treatment that uses low-intensity laser light to reduce inflammation and accelerating the body’s natural healing process, making it particularly effective for nerve-related pain.
When to Seek Medical Advice
It’s essential not to ignore symptoms like burning, tingling, or numbness in your feet. While these sensations might seem minor, they often will not go away on their own and can worsen, leading to chronic pain, muscle weakness, or even permanent nerve damage. If you’re experiencing persistent discomfort, it may be time to see a podiatrist.
