“I am concerned about late side effect (left eyelid drooping) of dysport injection”

Hello. Two weeks ago I had Dysport injection on my forehead and eyes ares. the day after theinjection I had some headache and drooping eyelids and soon recovered from the side effects.

Two days ago I noticed that my left eyelid drooped again. The right eyelid is fine. I am very concern since this is the third time I have this type of treatment in intervals of 6 months and never had side effects before. However, my other 2 treatment were done with botox.
