Hi I am very worriedI have had botox on and off for a few years very conservative. Four days ago had botox in the glabella area. By day two, symptoms include itching all over, tired, sore throat, and swollen glads, some difficulty swallowing. I am a mother of 4 and scared. I decided after 8 months to go in to get the treatment of botox to look refreshed. Anyone else feel this way. I am taking ibuprophen and antihistamine. Helps a little. If I am allergic what will this get worse over time and how long will this last? Family does not know I get botox - always keptto self now feel foolish and scared - I do not want this to get in way of taking care of family and working.
