Hi thanks for your question.
Most probably you have injured temporal branch of fascial nerve
which supplies the frontal part of temporalis musle and takes the upward course after emerging infront of ear.The drooping of temporalis clould be due injury
of this branch.A portion of eyelid is also having nerve supply from fascial nerve.Injury to this branch may be responsible for strained eye lid.I don't feel any problem in getting Botox
on crows feet,however your Doctor can answer in better way.
Hope this answers your question.
