Well.... I've been eating what I call "Stupid Foods," and the devil patch on my right wrist is back, along with the bump in my left palm. These were gone when I was eating pristine.
Boat.... you might consider giving up the major food groups that cause inflammation.... gluten, sugar and dairy.... for a while, and noting improvements. I'd give it a couple months try before you draw conclusions.
When I gave those things up... I'm talking zero sugar... no fruit, zero on every food label, I could think more clearly, and weight dropped off in layers, dimples, and bumps so I looked like I did 25 years ago. This was unintentional.... like alchemy for me. I didn't intend to lose weight... only think more clearly. All about inflammation, and lightening the bodies toxicity load so it can process toxins on it's own, and heal our immune systems, IME.
I also ate healthy protein 3 times a day, along with ONE weekly gluten free carbohydrate choice. Honestly it was a lot of food. I was never hungry. When we give up junk foods, our bodies stop craving them, IME.
At some point, I could have started adding in things and seeing how my system handled it. Some things we're sensitive to and some we're not SO sensitive to, IME.
I hope you figure out the skin issues. It really could be food related.
