i had a botox injection in my R neck. 10 days later when the botox took effect in my shoulder, my R eye went blurry. It has bee

The botox also caused a painful pulling sensation.  My R neck area feels like my arm is holding a heavy suitcase that I cannot let go of.  Is the pulling sensation causing the vision problem?

I read online that the botox can enter into the brain.  Could this be the cause of the blurry vision?

I saw an Opthamologist, Neurosurgeon, Primary Doctor, and all appears normal.  MRI, Xray, Bone scans are all clean.  I do not have any other underlying conditions  (e.g. no diabetes, blood pressure is normal, cholesterol is low).
