Tingling in both legs after several days of liquid fasting is often related to low blood
sugar or an electrolyte imbalance, especially sodium or potassium, from limited food intake.
Next Steps
Add an electrolyte drink or a pinch of salt and
sugar in water today, and plan to break the fast gradually with regular meals rather than continuing much longer.
Health Tips
See a general physician if the tingling doesn't ease once you eat normally, or sooner if it spreads, or you feel weak or faint.
