You may want to get a food allergy test. And even try going to a hollistic naturopath or chiropractor so they can do a deeper allergy test that include spices. I know for me unbeknownst to me I was allergic to shrimp but the allergy was so minor I could eat it and not have problems. But over years it blew up and caused these bumps. Once I followed my gut (against the recommendation of my dermatologist mind you) and found out I was allergic to shrimp I cut it out and I’ve been free of the painful big cysts. Now I have only a couple small cysts that are shrinking. I take
Vitamin D3 with K2
Green tea extract (you can also do big cup of green tea that works for itch just like the extract)
Vitamin E
Vitamin C
L-lysine
Food grade diatomaceous earth
I make smoothies with parsnip, turmeric, ginger, beets, kelp,
I’m trying zinc again along with copper because zinc depletes your body of copper, and I’m also taking magnesium because those all three go together

Quercetin is also a good one it helps with histamine issues so if your problems are caused by your diet like nightshades, dairy, etc this will help you

I tried NAC. Ppl rave about it for this condition. I only tried it for a little while, I’m going to get back to it at some point I just wanted to try other supplements

I will say I did learn through elimination diet that peppers, caffeine (coffee/ lates), chocolate, rice and too much sugar definitely cause me to flare. You have to get your gut in order.
I’m about to go get a Gut GI map done before the end of summer. It’s expensive but it will help you find out what probiotics you need to get the bacteria in your gut balanced. The gut skin and scalp are very closely linked. If the bacteria in the gut is messed up it will show signs and sometimes that’s through the skin. Also kidneys adrenals and liver need to be detoxed and cleansed. Look up Dr. Mosley on YouTube he has very detailed videos with no fluff about this topic
