Leg Pain: Causes, Treatments, and When to See a Doctor

Frequent foot pain?

Hello Doctor: I am 30 years old, unmarried, 160 cm tall, and weigh 80 kg.
Whenever it rains or when I am exposed to a fan or air conditioning, my feet become very sore, to the point where I feel like I need to squat down.
My knees also hurt.
Sometimes, even without a change in weather or exposure to a fan or air conditioning, I experience this pain quite frequently.
A few times, I have also felt pain in my knees when going up and down stairs.
What could be the issue? Which department should I visit if I want to see a doctor? What should I pay attention to in my daily life?

More Info

Leg pain can be a complex issue, especially when it is associated with specific triggers like weather changes or exposure to cold air. Given your age and the symptoms you've described, there are several potential causes for your discomfort, and understanding these can help you seek the appropriate treatment.

Possible Causes of Leg Pain
1. Weather Sensitivity: Many individuals report increased pain during rainy or cold weather. This phenomenon is often linked to changes in barometric pressure, which can affect the joints and surrounding tissues. Conditions like arthritis can be exacerbated by weather changes, leading to increased pain and discomfort.

2. Knee Pain: The pain you experience in your knees, especially when going up or down stairs, could indicate issues such as patellofemoral pain syndrome (often referred to as "runner's knee"), tendonitis, or even early signs of osteoarthritis. These conditions can cause pain due to overuse, improper alignment, or degeneration of the cartilage.

3. Muscle Strain or Overuse: If you are physically active or have recently increased your activity level, muscle strains can occur, leading to pain in the legs. This can be particularly true if you are not accustomed to certain movements or if you have a sedentary lifestyle.

4. Circulatory Issues: Conditions affecting blood flow, such as peripheral artery disease (PAD), can cause leg pain, especially during physical activity. If you notice pain that worsens with exertion and improves with rest, this could be a sign of a circulatory issue.

5. Nerve Issues: Sciatica or other nerve-related issues can also cause leg pain. If the pain radiates down your leg or is accompanied by numbness or tingling, it may indicate nerve involvement.

When to See a Doctor
Given the recurrent nature of your symptoms, it would be wise to consult a healthcare professional. You should consider seeing a primary care physician first, who can evaluate your symptoms and refer you to a specialist if necessary. Depending on the findings, you may be referred to:
- An orthopedic specialist for knee-related issues.

- A rheumatologist if there is suspicion of an inflammatory condition like arthritis.

- A neurologist if nerve involvement is suspected.

Recommended Actions
1. Keep a Pain Diary: Document when your pain occurs, its intensity, and any activities that may trigger it. This information can be valuable for your doctor.

2. Physical Activity: Engage in low-impact exercises like swimming or cycling to strengthen your leg muscles without putting too much strain on your knees.

3. Weight Management: Given your height and weight, maintaining a healthy weight can reduce stress on your knees and lower extremities.

4. Heat and Cold Therapy: Applying heat or cold packs can help alleviate pain. Heat can relax and soothe muscles, while cold can reduce inflammation.

5. Over-the-Counter Pain Relief: Nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen or naproxen can help manage pain and inflammation, but consult with a healthcare provider before starting any medication.

6. Stretching and Strengthening Exercises: Incorporate stretching and strengthening exercises for your legs and knees to improve flexibility and support.

Conclusion
Leg pain, especially when associated with specific triggers, can be indicative of various underlying conditions. It's essential to consult with a healthcare provider to determine the exact cause of your pain and to develop an appropriate treatment plan. Early intervention can often lead to better outcomes and improved quality of life.
