Food allergy HELP 😭!

JK

Y’all I’m at my wits end with this. I don’t know what is bothering my LO & I can’t figure it out! Some days I’m convinced it’s everything other days I think it’s nothing (food at least). I’ve talked to his Dr. He’s too young to allergy test & they said without eliminating & then reintroducing there’s no way to really know. The thing is I just keep eliminating more & more & he keeps having reactions 😭.

I don’t want to make this too long, but I want to give enough back story. We started introducing food right at 6 months via a somewhat modified version of BLW. One of those modifications was we did introduce individual foods and wait between food introduction because there are allergies in our families & that was a concern. We had 0 reactions or issues until about a month & 1/2 ago (about 7 1/2 months old). We gave him fish for the 1st time for dinner & the next morning he had a bright red rash all over his face, chest, belly & back along with being slightly wheezy. We took him to urgent care, but by the time they saw us his wheezing was gone & rash improved enough they just checked him out & sent us home. Rash gets progressively better over the next few days. Then about a week later he starts a new rash, but slightly different & starts small & gets progressively worse. After a few days and when it gets to be it’s worst, I make an appointment and take him to the Dr. They give him steroids & hydrocortisone to clear it up, we talk through everything it could be & agree until it clears & we reintroduce some things there’s no way to know , could also be eczema.

It gets better with meds, never fully goes away and over the last month or so will get better then worse then better etc. he’s had a handful of more immediate reactions with meals but all with things he’s had before. I started keeping a food log which based on that I though legumes could be a culprit. I eliminated all of those & he was getting clearer & clearer for a week or so with no flare ups... then the rash starts coming back again, I eliminate a few more things, last night we are eating (all things he’s had with seemingly no reaction) & his chin starts to turn red, then chest & back, hives everywhere 😭. It cleared up by bedtime and his breathing stayed clear, but I’m just so lost.

I’m thinking of going back to just 1 food and slowly introducing foods 1 at a time again. But my now almost 9 month old loves to eat & I really don’t want to start from scratch & I’m not convinced it’ll help 😭.

Please someone tell me they’ve gone through this & have some good advice !
