I’m sorry to hear that.
I highly suggest to carefully monitor what you eat. To get started I’d absolutely eliminate any gluten and any nightshade vegetables!!!
I suffered from having fissures (small cuts) around my annus and outside of my vaginal area. I suffered for about 7 years. It got worse about a year ago. My doctors took tests - no celiac disease, no allergies. Dermatologists wanted to give me cortisone cream, I tried that once, didn’t help.
A year ago a friend of mine suggested to eliminate gluten … that helped instantly!!!
Then I’ve got cuts again - I had eaten tomatoes. I looked up tomatoes and find out everything about nightshade vegetables. I also learned that the poison/ natural pesticide (Solanin, Tomatin) that’s in nightshades is also in: apples, blueberries, strawberries, cherries. I’m very strict with food. As long as I eliminate gluten and solanin, I don’t have these cuts.
I highly suggest to NOT eat any of those for at least 1-2 month and see if it helps.
Good luck and let us know if it helps.
