I’ve got Botox and juvederm. Had Botox only two times in the past, and had some light itch on my foot and forehead. After last injections plaques in my throat, got cravit antibiotic (used in the past). One week after the cosmetic procedures, I developed acute itch all over my body flushing red face, and difficulty swelling.The injector told me it was maybe hay fever. My GP gave me antihistamine for 2 months but she’s unsure it was hay fever. I’m wondering if I might be caused by the injections.
