Sudden pain?


Hello, recently my family members tested positive for COVID-19, and I also tested positive.
Then yesterday, I suddenly felt soreness in my thigh (it doesn't hurt when standing or walking, but after squatting, there is pain near a specific point on the right side of my thigh, and it hurts a little when pressed).
I'm worried that it might be a nerve injury, so today I went to a nearby clinic, and the doctor said it should just be a strain, not a post-COVID complication.
I want to ask the doctor, is this soreness a sign of long COVID? Also, I only kicked my legs lightly yesterday, so I'm not sure if I strained it too much.
The clinic prescribed a topical analgesic, and since this is my first time experiencing this, I was told I don't need to take any medication or get an X-ray, just apply the ointment.
Does this mean that a muscle strain will heal on its own over time? Can I also consider acupuncture for treatment in this situation? I have been taking traditional Chinese medicine to help my body recover after the COVID diagnosis, but I'm concerned if acupuncture is appropriate for this strain.
Should I just stick to applying the ointment? Thank you.

Hello, indeed some people with long COVID experience muscle soreness, which can be difficult to distinguish from strains.
However, the management is the same: rest and heat therapy, as well as anti-inflammatory ointments such as Soothe, or acupuncture, can help alleviate symptoms.
Thank you for your question.

More Info


Sudden thigh pain can be concerning, especially when it arises unexpectedly after physical activity. Based on your description, it seems that you may be experiencing a muscle strain, which is a common injury that occurs when the muscle fibers are overstretched or torn. This can happen during activities that involve sudden movements or excessive force, such as kicking a ball.

Causes of Sudden Thigh Pain
1. Muscle Strain: As mentioned, this is the most likely cause of your pain. Strains can occur in any muscle, but the quadriceps (the large muscle group at the front of the thigh) is particularly susceptible. Symptoms typically include localized pain, tenderness, and sometimes swelling.

2. Tendon Injuries: Tendons connect muscles to bones, and they can also be strained or torn. This can lead to pain that may feel similar to a muscle strain.

3. Nerve Issues: While less likely in your case, nerve compression or irritation can cause pain in the thigh. This is often accompanied by other symptoms such as tingling or numbness.

4. Other Conditions: Conditions such as bursitis or hip joint issues can also cause pain in the thigh area, but these are less common in the context of a sudden onset after physical activity.


Treatment and Recovery
1. Rest: It's crucial to allow your body time to heal. Avoid activities that exacerbate the pain, especially those that involve bending or putting pressure on the affected area.

2. Ice Therapy: Applying ice to the affected area can help reduce swelling and numb the pain. It's typically recommended to ice the area for 15-20 minutes every hour as needed.

3. Topical Treatments: The medication your doctor prescribed, such as a topical analgesic like "Soothe," can help alleviate pain and inflammation. These are generally safe to use and can be effective for mild strains.

4. Over-the-Counter Pain Relief: If the pain is significant, you might consider taking over-the-counter nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen or naproxen, provided you have no contraindications to these medications.

5. Physical Therapy: If the pain persists, physical therapy may be beneficial. A physical therapist can provide exercises to strengthen the muscle and improve flexibility, which can help prevent future injuries.


Acupuncture and Alternative Treatments
Acupuncture can be a complementary treatment for muscle strains. It may help relieve pain and promote healing by increasing blood flow to the affected area. However, it's essential to consult with a qualified practitioner who understands your condition and can tailor the treatment to your needs.

Long COVID Considerations
Regarding your concern about long COVID, while some individuals report lingering symptoms after recovering from COVID-19, muscle strains typically do not fall under this category. Long COVID symptoms often include fatigue, cognitive issues, and respiratory problems rather than localized muscle pain. However, if you experience other concerning symptoms or if the pain does not improve with conservative treatment, it would be wise to follow up with your healthcare provider for further evaluation.


Conclusion
In summary, it sounds like you are dealing with a muscle strain, which should improve with rest, ice, and topical treatments. Acupuncture can be a helpful adjunct therapy, but ensure you communicate your recent injury to the practitioner. If your symptoms do not improve or worsen, consider seeking further medical advice. Always listen to your body and give it the time it needs to heal properly.
