Swelling and pain in the dorsum of the foot?


Hello, Director Chen! My right foot (about 4 centimeters near the ankle) suddenly became so painful during my daily walking routine that I couldn't continue.
After applying a hot compress and using a topical anti-inflammatory, there is a red swelling, and the pain has persisted for 3 days.
Is it correct to use heat for sudden pain? Additionally, how can I prevent pain while walking? Thank you for your response!

1.
It may be tendonitis of the extensor hallucis longus or the extensor digitorum communis.

2.
During the acute phase, apply ice for 10 minutes; in the chronic phase, switch to heat therapy.
Anti-inflammatory ointments can also be used.

3.
Performing a plantar flexion movement (like pressing the gas pedal) can help reduce dorsal foot pain due to the action of the antagonistic muscles.

4.
When walking, avoid excessive dorsiflexion of the foot; using a flat-footed walking technique can help prevent pain.

More Info


Sudden foot pain can be a distressing experience, especially when it interrupts your daily activities like walking. Based on the symptoms you've described—localized pain near the ankle, redness, swelling, and persistent discomfort despite heat application—there are several potential causes and preventive measures to consider.


Possible Causes of Sudden Foot Pain
1. Tendinitis: Inflammation of the tendons around the ankle can lead to sudden pain, especially if there has been an increase in activity or strain on the foot. This is common in individuals who may not have a regular exercise routine but suddenly engage in more walking or physical activity.

2. Ligament Sprain: A sudden twist or awkward step can cause a sprain, leading to pain and swelling. This might not always be associated with a specific injury you remember, as minor sprains can occur without a clear incident.

3. Plantar Fasciitis: Although typically associated with heel pain, inflammation of the plantar fascia can sometimes manifest as pain in other areas of the foot, especially if the foot structure is compromised.

4. Gout: This type of arthritis can cause sudden and severe pain, often in the big toe but can also affect other areas of the foot. It is characterized by redness and swelling.

5. Infection: If there is significant swelling and redness, an infection could be a possibility, especially if there are any cuts or wounds on the foot.

6. Stress Fracture: Overuse or repetitive stress can lead to tiny fractures in the bones of the foot, which can cause sudden pain.


Immediate Management
- Rest: Avoid putting weight on the affected foot to prevent further injury.

- Ice: Applying ice packs for 15-20 minutes every few hours can help reduce swelling and numb the pain.

- Elevation: Keeping the foot elevated can also help decrease swelling.

- Over-the-Counter Pain Relief: Non-steroidal anti-inflammatory drugs (NSAIDs) like ibuprofen can help manage pain and inflammation.


Preventive Measures
1. Footwear: Ensure that you are wearing supportive shoes that fit well. Avoid high heels or shoes with inadequate arch support, as they can exacerbate foot problems.

2. Gradual Increase in Activity: If you plan to increase your walking distance or intensity, do so gradually to allow your body to adapt.

3. Stretching and Strengthening: Incorporate foot and ankle stretching and strengthening exercises into your routine. This can help improve flexibility and strength, reducing the risk of injuries.

4. Foot Orthotics: If you have flat feet or other structural issues, consider using orthotic inserts to provide better support and alignment.

5. Warm-Up: Always warm up before engaging in physical activity. This prepares your muscles and tendons for the exertion ahead.

6. Listen to Your Body: If you experience pain, don’t push through it. Take breaks and allow your body to recover.


When to Seek Medical Attention
If the pain persists despite home treatment, or if you experience severe swelling, inability to bear weight, or fever, it is essential to consult a healthcare professional. They may perform imaging studies like X-rays or MRIs to determine the underlying cause of your pain and recommend appropriate treatment.

In summary, while sudden foot pain can be alarming, understanding its potential causes and implementing preventive strategies can help manage and reduce the risk of future episodes. Always prioritize your foot health, as it plays a crucial role in your overall mobility and quality of life.
