Sorry to hear you're going through this. As someone who has battled Psoriasis for over 8 years, I've tried everything. Eating actual food (eggs, fruit, steak etc.), walking in the sun and also intermittent fasting has been the only things that helped my flare ups. Of course corticosteriods are a last resort for short term relief. I hope you find what works for you. Sending positive energy your way Eliza
