Hello,
After reading your query, i have few questions for which i need answers before completing diagnosis like :
1. Which body part are you talking about?
2. Since how long you have this vibration?
3. What is your physical activity level?
And also, as i am an ayurveda consultant, i do need your prakriti analysis.
Generally, muscle vibrations are nothing to worry off. It could be due to magnesium deficiency or stress or anxiety or over physical activity.
Next Steps
