How long does the blurred vision last after Botox injections?

I had Botox 5 weeks ago. Day 8 started having very bad headaches, blurred vision, dizziness and anxiety. All the symptoms went away,the blurred vision persist. What are the reports of the length of duration of blurred vision in patients complaining of the symptoms?. I have had Botox for the past 4 yrs without complications. However this time the doctor gave me Botox in the inner part of the eyes, and I think that might be the problem causing blurred vision. Will it last the whole 3 to 4 months?
