Muscle or nerve twitching persists?


Hello Doctor, I have been experiencing an increasing frequency of twitching on the inner side of my left thigh.
I have sent two short videos for your preliminary assessment.
https://youtu.be/avo45DGnfH0 https://youtu.be/csDjJ8YggPs Could you please determine whether this is a neurological twitch or a muscular twitch? In the meantime, before I can see a neurologist, what can I do to alleviate this condition? (For example: drink more water? exercise more?) Thank you.

Hello Mr.
Ben: Your YouTube video shows twitching of the vastus medialis muscle in the quadriceps.
This muscle twitching is primarily related to inflammation, which can be caused by exercise, acute viral infections, anxiety, and medication use.
Among these, prolonged exercise is one of the main reasons for muscle twitching.
Common medications that can lead to twitching include excessive caffeine.
Many people find themselves in a vicious cycle where mild twitching causes anxiety, which in turn exacerbates the twitching, leading to further panic and anxiety in the patient.
If the symptoms persist, it usually indicates upper motor neuron damage, resulting in abnormal signal transmission that may cause muscle twitching.
If your symptoms are accompanied by pain or numbness, the likelihood of peripheral nerve compression is quite high.
Peripheral nerve examinations can typically be assisted by electrophysiological studies.
Nerve conduction studies assess the conduction velocity and waveform of large fiber nerves.
Electromyography (EMG) evaluates the muscle response in the area supplied by the nerve.
It is advisable to consult a neurologist specializing in peripheral nerves, as they have more experience with EMG diagnostics.
Please ensure to practice self-protection, maintain cleanliness and disinfection, and adhere to new epidemic prevention measures before and after seeking medical care.
Thank you for your inquiry, and feel free to discuss any related questions! Wishing you good health, peace, and joy.
Dr.
Jiang Junyi, Taoyuan Medical Center, cares for you.

More Info


Muscle twitching, also known as fasciculation, can be a perplexing symptom that often raises concerns about underlying neurological issues. In your case, the increasing frequency of twitching in the inner thigh of your left leg warrants attention, especially since it can be indicative of various conditions affecting either the muscles or the nerves.

To differentiate between muscle twitching and nerve-related issues, it's essential to consider the characteristics of the twitching. Muscle twitching typically presents as involuntary contractions of muscle fibers, which can occur without any associated weakness or pain. On the other hand, nerve-related twitching may be accompanied by other symptoms such as numbness, tingling, or weakness in the affected area. The videos you provided could help a healthcare professional assess the nature of the twitching more accurately.

In the interim, while waiting for your appointment with a neurologist, there are several strategies you can employ to potentially alleviate your symptoms:
1. Hydration: Dehydration can lead to muscle cramps and spasms, so ensuring you drink enough water throughout the day is crucial. Aim for at least 8-10 glasses of water daily, and consider increasing your intake if you're physically active.

2. Electrolyte Balance: Along with hydration, maintaining a proper balance of electrolytes such as potassium, magnesium, and calcium is vital for muscle function. Foods rich in these minerals, like bananas, leafy greens, nuts, and dairy products, can be beneficial. You might also consider electrolyte drinks, especially after exercise.

3. Regular Exercise: Engaging in regular physical activity can help improve muscle tone and reduce twitching. Focus on low-impact exercises such as walking, swimming, or cycling, which can enhance circulation and muscle health without overexerting yourself.

4. Stretching and Relaxation: Incorporating stretching exercises into your routine can help relieve muscle tension. Gentle stretching of the thigh muscles may reduce the frequency of twitching. Additionally, practices such as yoga or tai chi can promote relaxation and improve muscle control.

5. Stress Management: Stress and anxiety can exacerbate muscle twitching. Techniques such as deep breathing, meditation, or mindfulness can help manage stress levels and may reduce the occurrence of twitching.

6. Avoid Stimulants: Reducing or eliminating caffeine and other stimulants from your diet may help if you notice that your symptoms worsen after consumption.

7. Sleep Hygiene: Ensure you are getting adequate rest, as fatigue can contribute to muscle twitching. Aim for 7-9 hours of quality sleep each night.

8. Monitor Symptoms: Keep a journal of your symptoms, noting when the twitching occurs, its frequency, and any associated activities or dietary habits. This information can be valuable for your healthcare provider during your evaluation.

While these strategies may help alleviate your symptoms, it is essential to consult with a healthcare professional for a thorough evaluation. The neurologist may recommend tests such as electromyography (EMG) or nerve conduction studies to assess the function of your muscles and nerves. They will also consider your medical history, any family history of neurological conditions, and other relevant factors to arrive at a diagnosis.

In conclusion, while muscle twitching can often be benign, it is crucial to monitor your symptoms and seek medical advice, especially if they persist or worsen. By taking proactive steps to manage your symptoms and maintaining open communication with your healthcare provider, you can work towards understanding the underlying cause of your thigh symptoms and finding appropriate relief.
