Botox inj. between my eyebrows was Sept. 3, 2014. I've had 3 inj. ( 4 - 7 months apart). No issues except mild headache once. Late Nov. left eye completely dilated for approx. 8-10 hrs. Only symptom had been itching eyes for several days. (perhaps allergies)? Since then I've had periodic headaches mainly behind my right eye. In the last three weeks my right eye has now dilated 5+ times periodically, lasting only minutes. CT sinuses was clear. Any Likelihood of late effect of Botox?
