Started Botox treatments for a hemifacial spasm in the last year. Had 3 treatments so far with the most recent in early December. Treatments seemed to be working for the last year; however two weeks after my last injection I had a severe case of food poisoning (had both diaherria and vomiting). Diaherria persisted for a week so started taking probiotics because doctor recommended it. Shortly after all of this my hemifacial spasm came back in full force as if I never had the Botox shots.
