Under eye muscle destroyed from Botox?

Hi, 7 mos ago I received jelly roll Botox from a nurse injector at my derm. Two years of great results from btx, this was first under eye. My eyes swelled horrifically and created ‘planes’ of fluid where under eye and cheek meet. Left eye healed, right eye has a horizontal line running through under eye and dramatic wrinkles. Three derms cannot explain, a plas surg said another year from now *may* lead to recovery, if not a lower bleph is only option. Does this make sense? Other options?
