Is it a common side effect to have huge cheeks after botox? (Photo)

i had botox on crows feet area. i had it before , but with different provider. this time i had a bruise under my eye near the cheek area (never happened before bc i dont think my usual provider injects that area) two days later my cheeks started to puff up. it has been two weeks and they decreased a little, but they are still puffy. is it because of botox? i am super upset :-( is it true that this may last 6 months?
