Benzo taper causing rashes/angioedema?

Sorry for the weird question. I’m a few months into a very slow taper from a “low dose” of klonopin and since starting, I’m having a TON of “sensitivities” and “allergy” issues. I put those in quotes bc I’m not allergic to most anything common.

I’ve been allergy tested twice since starting and the only thing I’m reacting to on testing is alternaria, a fall mold.

But right now, I can’t even touch my dog without my hand going numb, feeling swollen and I’m also having bouts of burning pain. The same happens on my feet. I’m noticing I’m way more rashy too. I just feel so swollen I’m losing my mind. But it’s not super visible. I think it’s messing with my nerves and making me super sensitive but I thought I’d ask here to see if anyone has experience.

My doctors (allergist and neurologist) have NO clue about this btw. I’ve already asked and got shrugs. I’ve also asked around the benzo withdrawal community but gotten limited response.

My allergist approved 4 Zyrtec a day but I’ve only tried 2, which haven’t helped. She also said I could try 2 Zyrtec, 2 Allegra.

Anyone faced similar issues or have insight? I’m really upset as I love my dog so much and this feels so random but I can’t touch my dog anymore 😭
