Experiencing worsening autoimmune symptoms?

Has anyone had any experience with this? (we have a drs appointment wednesday). Remember my dr had masses on her neck ? they keep getting bigger and never disappear and have multiplied. The dr said they appeared to be benign based off of ultrasounds. They didn’t want to do a biopsy because of the major risks, so we would have to just monitor. Her dr told me the other day she wanted us to do blood work because it’s never been done and she may have an auto immune disorder. She has an allergic reaction to her own poop, her drool, her throw up, any of her fluids

touch her she immediately breaks out. When I give her a bath her eyes get all red and puffy from just water. Her reactions are getting worse. She has an appointment with her dr on wednesday and we will likely had a referral to the allergist and immunologist. Has anyone dealt with this ?
