Yes I’m thinking so 

I’m almost 23 with celiac disease but if you would ever like to talk i’d be open to it 

As Scott suggests, look into dermatitis herpetiformis. Also the rash there could be from SIBO small intestinal bacterial overgrowth or candida. If your regular doc won't investigate those possibilities, consider going to a naturopathic doc or integrative medicine doc.

The forms of vitamins really mattered for me, maybe not for everyone but very much for me. Learned so much here. This b12, recommended by @Ennis-TX has really helped me since diagnose.  I can tell when i run out that i don't feel as good. LIQUIDHEALTH Vitamin B12 Methylcobalamin Liquid Drops with Sublingual Hydroxocobalamin - Boost Energy, Support Immune System, Improve Memory & Concentration - Vegan, Sugar Free, Non-GMO (2 Pack) https://a.co/d/c3cxXt7   i also had RLS, one of my few noticeable symptoms before diagnosis. It rears up when I slack off the supplements or drink wine. I found 2 of these a day keeps it at bay, get it very rarely now: Limited-time deal: ANDREW LESSMAN Circulation & Vein Support for Healthy Legs 60 Capsules - High Bioactivity Diosmin, Butcher's Broom, Visibly Reduces Swelling & Discomfort in Feet, Ankles, Calves, Legs https://a.co/d/7int9i9   I also take the procapslabs.com b complex, it has the methyl forms, which makes a difference for me: ANDREW LESSMAN High Potency B-Complex 180 Capsules - with High Levels of Folate Complex & Biotin, Promotes Cellular Growth, Energy, Immune Function, Detoxification, Fat Metabolism & More https://a.co/d/4fkAmFx   I also take extra thiamine, in form benfotiamine, as recommended by @knitty kitty which tremendously helped asthma. 

Perhaps you'll need to mix your own cocktails?
