I had Botox injections in my crows feet, 11", above my brows and upper lip. 15 minutes after leaving the Dr's office my throat started to swell shut, my heart was racing, my voice is hoarse and I have difficulty swallowing. Also a sight vision loss in one eye. This has resulted in two ER visits and an overnight hospital stay. I am being treated with prednisone, benadryl and pepcid (basically like like an allergic response). Can the Botox continue to spread further in my body and become botulism?
