Cannot Move Upper Lip After Botox on Bunny Lines

Last week, I had Botox injected in the "bunny lines" of my nose. I did go 2 times to add a bit more on one the one side of my nose. Now, I can barely move my upper lip. I see you mentioned this was a possibility from having the injections in that area. Will the movement of my mouth stay this way as long as the Botox holds out? Is this a sign of something dangerous being wrong? I would appreciate your advice on this. Thank you.
