Feeling body vibrations and reduced awareness for a couple of hours may occur due to nerve-related problems, anxiety, weakness, or low blood sugar. Try to rest well, eat regular meals, and stay hydrated. Because the episodes last for a long time and affect your awareness, it is important to consult a doctor. A medical check-up can help find the exact cause and provide proper treatment.

Swelling in one foot with a burning sensation in both feet may occur due to nerve irritation, circulation problems, injury, or conditions such as diabetes. Keep the feet elevated while resting and avoid standing for long periods. Wearing comfortable footwear and maintaining good blood sugar control may also help. Consult a doctor for proper examination and treatment if the swelling or burning continues.
