Yes, same thing happened to me. For the first few weeks. It was like a miracle. But then plateaued, I'm only a few months in and have discovered that I was eating some starchy things that I thought weren't starchy… Like broccoli stems cooked. So it could be because of these things that my results are skewed. My advice is just ride it out doing a no starch no sugar diet for a few months, then take bone broth to prevent stomach upset and go down to carnivore and celery and salt for 2 weeks. It will probably remove the remainder of the pain so you can add things one food at a time and know what effects what. I'm new here, so keep that in mind but that's my plan

I have commented on here before, but thought I’d chime in again with my experience as of late. I went strict Autoimmune Paleo (AIP) combined with no sugar and low starch for a couple months. I emphasized foods that are supposed to help heal (leafy greens, onions, bone broth, fish, olive oil, etc.). I have seen such amazing results. I have been low to zero pain for about a year now. I think it’s important to focus on gut healing while you are NSD, otherwise you will continue to suffer with every accidental ingestion of starch. I also took some supplements recommended to me including Glutamine, fish oil, fermented cod liver oil, vitamin D, etc.
