Hi and nice to meet you. So glad you found your way here, though of course I wish you did not have this pain. Please know that there is a very wide range of symptoms and pain, so you can feel free to "let it all out" and express how you are feeling, and thus get support. You will be heard and listened to with compassion.
I definitely have experienced getting worse before better with NSD and I've read an explanation why, but can't recall how to describe it, sorry! Along with that, just eliminating certain foods such as gluten and so on can start a kind of process that makes your body hurt and crave them, but then you'll feel better.
Take care and keep in touch,
