Hello, Thank you for your query. I understand your concern and anxiety. Your description of symptoms seem to be related to anxiety issues or public speaking. This is common and can be helped with personality recognition and identifying the underlying cause. This needs a complete clinical examination to make sure there is no actual weakness in muscles and a psychological evaluation to identify the cause of anxiety and help deal with through counseling and practice. Please see your doctor to guide you through the process. I believe it is likely due to anxiety. Persistent and consistent efforts from your side will help you with this. There are no quick fixes. There will be ups and downs but you must persevere. Hope this helps. Please let me know if there is anything else I can help you with. Wish you good health
