I got tongue sores (looks like blisters) after fasting, I thought it was due to electrolytes deficiency. I repeated a 2 day fast this week after supplementing b12, iron and electrolytes for a week. Unfortunately it didn’t help, I got the tongue sores again towards the end of the second day.
What could be the reason?
I’m not a doctor but if I could guess:
On your tongue = perhaps inflamed taste buds.
In and around your mouth = perhaps HSV 1
Both fairly common and are usually brought on by stress which isn’t surprising as fasting is a stressor.
