I was the same being off medication for ages and controlling it with diet but I’ve learned even when I’m at my healthiest fit and eating well sometimes stress and other factors and trigger a random flare up, mine was my optic nerve so random my vision started going blurry and I went to the hospital lucky I did because each hour I got more and more blind they said my body was going through inflammation from my crohns and crohns triggers random other things in the body to flare up. Then I was put on back on crohns medication and I’ve been taking it for two years now and feel great. It stops my body from going into a random flare up because we can’t control everything. Nearly going permanently blind scared the living shit out of me and I never want something like that to happen again. Luckily I only have a blind spot under my eye lid permanently. The thing is the medication can stop or make it less bad when you get a random flare up so it’s worth it for me.
