Foot Pain: Causes and When to Seek Medical Help

Foot problems

Hello doctor, I have been experiencing a pulsating pain in my left foot, from the dorsum to the ankle (I'm not sure if this description is accurate).
This issue has occurred before, but previously the pain, rated on a scale of 1 to 10, was around 6 to 8 and mostly happened when the weather turned very cold.
It has only occurred in my left foot, with no issues in my right foot.
The pain usually lasts for about 2 to 3 days and then disappears, so I haven't gone to the hospital for an examination.
However, recently, the pain has been persistent at a level of about 3 to 5, and it started suddenly even though the weather isn't very cold, which has made me a bit worried.
Additionally, I have a mild L4-5 disc herniation, but it doesn't affect my daily life.
Could this be related? If I need to see a doctor, which specialty should I consult, and what potential issues could the doctor suspect?

More Info

Foot pain can arise from a variety of causes, and understanding the underlying issues is crucial for effective treatment. Based on your description, it sounds like you are experiencing a pulsating pain in your left foot, particularly around the ankle area, which has been recurrent but is now more persistent. The fact that this pain has been exacerbated without a clear trigger, such as cold weather, raises some concerns that warrant further investigation.

Possible Causes of Your Foot Pain
1. Musculoskeletal Issues: Given your history of mild L4-L5 disc herniation, it's possible that your foot pain could be related to nerve compression or irritation stemming from your lower back. The lumbar spine houses nerves that innervate the lower extremities, and issues in this area can manifest as pain, tingling, or weakness in the legs and feet.

2. Peripheral Neuropathy: Conditions such as diabetes or vitamin deficiencies can lead to peripheral neuropathy, which may cause sensations of pain, tingling, or numbness in the feet. If you have any risk factors for these conditions, it might be worth exploring.

3. Circulatory Issues: Pulsating pain can sometimes be associated with vascular problems. Conditions like peripheral artery disease (PAD) can lead to reduced blood flow to the extremities, causing pain during rest or activity.
4. Tendonitis or Bursitis: Inflammation of the tendons or bursae around the ankle can lead to localized pain. This is often exacerbated by activity or certain positions.

5. Gout or Arthritis: Although you mentioned that the pain is not as severe as before, conditions like gout can cause intermittent pain and swelling in the joints, typically affecting the big toe but can also involve other areas of the foot.

When to Seek Medical Help
You should consider seeking medical attention if:
- The pain persists or worsens over time.

- You experience swelling, redness, or warmth in the affected area.

- You have difficulty walking or performing daily activities.

- There are changes in skin color or temperature in your foot.

- You experience any numbness or weakness in your foot or leg.

Which Specialist to See
Given your symptoms and medical history, it would be advisable to consult with a physiatrist (a specialist in physical medicine and rehabilitation) or an orthopedic surgeon who specializes in foot and ankle issues. They can perform a thorough examination, possibly including imaging studies like X-rays or MRIs, to determine the exact cause of your pain.

Conclusion
In summary, while your symptoms could be related to your existing back condition, they could also stem from other musculoskeletal, neurological, or vascular issues. A comprehensive evaluation by a healthcare professional is essential to pinpoint the exact cause and develop an appropriate treatment plan. Early intervention can often lead to better outcomes, so don’t hesitate to seek help if your symptoms persist or worsen.
