“No longer smiling”

Had juvederm done in my upper lip area to get rid of those wrinkles...its been about 7 days and although my lips look great and my wrinkles are gone, I am no longer able to create a smile where my upper teeth are showing and have difficulty talking. No my lips aren't huge and they didn't overfill me...the doctor was very conservative and if you saw me you probably wouldn't even notice I had it done. I can't bear the thought of not being able to smile for 6 months especially since I have a customer service type of job where facial expressions are important. Has any one else had this problem? I think I am going to schedule a recheck and see if I can get it reverses. Live and learn.
