I have Celiac Disease. In addition to that I have scalp and nail psoriasis, Vitiligo, Hashimotos Thyroiditis, Posterior Blepharitis, ADD, anxiety, depression, and lactose intolerance. I'm seeing a urologist in a few days to see if I have Interstitial Cystitis or possibly bladder cancer.
I'm not sure of how likely it is to naturally have all of that...
