I just completed a 150-hour water fast with salt and potassium. After probably 4 days, my back (just below my bra) would start to really pain me. I had this same experience years ago when juice fasting. It seems way too high to be my kidneys or even my small intestine.
Most days I would have it for a couple of hours and it would go away. Today I have had it for several hours. I decided to break my fast to see if that would help. Nope. I can’t hold any position very long because of the pain.
A couple of months ago I spoke with one of the IDM counselors who said she had never heard of such a thing.
I am hesitant to head to a doctor since there’s no way I’d do medication.
Any ideas of what it could be and what I can do to ease/prevent it?
Many thanks.
