Pain in back hips and butt at day 4 of extendedfast

(Cheryl Meadows) #101

So I got to test out my theory: I fasted for 5 days and my blood sugar was at 50 when I got out of bed. Sure enough I got that awful, excruciating pain, except this time it was also in my arms and upper back. I thought I was gonna die, it was really, really bad. So, I raised my blood sugar back up with some juice but the pain remained. With no lessening of the pain, I took a potassium and calcium pill, and also drank a green smoothie, and out of desperation took two motrin. Finally the pain left and I don’t know what actually helped.
I read Hypoglycemia affects potassium levels. So my next theory to test is, before going to bed each night when doing a fast, is to take a potassium and calcium pill. But for sure the LOW blood sugar is the catalyst.
Stretching did not help at all.

Hi there, I was so thankful to find this site and this forum since I am experiencing horrible buttocks pain that shoots down my thighs. It sounds like what everyone else here is experiencing although I don’t have any lower back pain. I have fasted for many years every few months for up to three or four days and this time I try to seven day water fast. Everything was going very well up until the end of day 4 when I started experiencing the pain. It was so horrible by DAY6 that I couldn’t stand it anymore. I wasn’t getting good sleep because it hurt the most when I laid down as others are saying. It’s definitely not a caffeine thing because I don’t drink coffee or anything caffeinated. And I am not lean, I am about 40 pounds overweight so this definitely doesn’t just effect lean people as someone suggested. I got so close To reaching my seven day goal that I’m really disappointed about this unexpected setback.
Has anyone found out anything useful? I’ve been following the advice in Dr. Jason Fung’s book, the complete guide to fasting and although I’m not finished reading it yet I can’t find anything about this problem which really surprises me. The pain is constant…although it has gone from a nine down to seven since I stopped the fast two days ago (although I am still in ketosis).

I watched this video and tried these exercises while lying in bed. I was in so much pain that I was about to get up and pace but I watched the video, did the exercises felt better (but far from pain-free) and was able to fall asleep. Other stretches hadn’t helped. I thought it was interesting because I was becoming fully convinced that the problem was in the bone… because it was so deep (the theory that white blood cells are being dumped and produced in the marrow etc.). Anyway, thank you for your help. I appreciated getting to sleep! : )


Hello everyone,

Just completed a 5 day fast (first one). I experienced exactly as discussed in this thread.

The fix for me was an coffee enema. Severe aches and pains on day 4, lower back, hips, legs. Pushed through but even after I broke my fast I still had pain 2 days after. I decided to do an enema. Immediately after first evacuation I felt completely fine. And for rest of day and sleeping that night was finally normal.

Hope this helps.

I’m on day 2 of a 3 day water fast and I have extreme pain in my glute. Like someone is stabbing me. I put about 1/2 teaspoon of celtic sea salt in water, stirred until is was completely dissolved. The pain is completely gone and it’s been about 10 minutes since I drank it. The celtic sea salt I used is the one in the blue bag.


I am on day 15 of a 30 day water fast. I have always had lower back and hip pain for many years now due to muscle imbalance and a compressed disc in my lower back. So when the pain increased I didn’t connect it with the fast. It has gotten so excruciating at times that I broke down and had a piece of cheese or a couple of spoonfuls of plain yogurt just so I could take some Advil for the pain. I have read through this thread and the suggestions of possible causes don’t apply. I drink black tea to get caffeine so haven’t had any caffeine withdrawals, take bone broth with Himalayan salt for electrolytes every few days, take magnesium and occasionally add potassium to my tea. But I do have a theory that I think might be plausible. I was reading up on growth hormone during fasting. Most here say their pain starts at day 4ish. Growth hormone peaks at day 5 and helps maintain lean muscle mass. It also gets excreted at night which would explain the difficulty sleeping so many complain about as well. And studies have also shown an increase in lean muscle mass and decrease in fat stores on prolonged fasts. So it appears in addition to preserving lean muscle mass it may also somehow contribute to building of lean muscle mass? Anyways just a theory. Mine started around day 5 and igot excruciating. I went to chiro and massage, foam rolled, used my massage chair etc and while these things helped the results were short lived before the pain returned. I even did acupuncture and cupping. Now at day 15 I am finally getting some pain relief… It’s still there but bearable now. I wonder if things in my low back are also being healed which is a breakdown and rebuild process. So anyways just thought I’d share my experience and my thoughts on what this could be. Best wishes everyone!

I think this is a very interesting contribution to our quest to find an explanation. It has been a while ago I studied growth hormone, so I do not remember exactly: isn’t there also a relation/connection between growth hormone and the bones?


Yes. The article I read says “This HGH likely helps in the maintenance of lean mass – both muscle and bone.” And a scientific journal states " IGF-1 and HGH have both been shown to stimulate the growth and repair of adult articular cartilage. One reason for this cartilage growth can be that some cartilage cells have HGH receptors." Human growth hormone levels are significantly raised during fasting so it makes sense to me that the pain we experience could be the effects of it working in our bodies during prolonged fasts.


I have done a couple of 54 hour fasts with no problem, so I decided to try a long water-only fast. Today is day 11 and the pain started on the evening of day 9, and I feel like I’m dying. It always starts when I lay down, but once it starts nothing makes it stop.
I had some keto-friendly soup last night that’s mostly bone broth, just so I could take some Tylenol. That and a heating pad dulled the pain so that I was no longer writhing and crying, but not enough to let me sleep.
For those theorizing this only happens to slimmer people-wrong. I’m at least 60 lbs overweight

What helped for me was sleeping on the floor for one night and my backpain was gone for the day , maybe you can try that.
