It sounds like Brisa is having a systemic allergic reaction to something - we may never know what, but possibly an insect sting - and in my experience oral antihistamines don't help a ton with these. Those big bubbles you see on her chest are likely hives. The thing is, if these have started after you gave ceteriZine, she likely needs more potent and immediate therapy in the form of injectable antibiotics and possibly anti inflammatories to arrest the reaction. I'd recommend a vet visit ASAP to get these medications.
