I had a fight and someone punched me on my upper lip, right now I can notice that my lip is Asymmetric when I smile? (photo)

First, stop fighting, give peace a chance ;). Seriously though, usually there is bruising and swelling and this can sometimes last out to 1 month, so be patient. If any asymmetry remains after that, then best to speak with your dermatologist about ways to correct the asymmetry, typically involving fillers like juvederm or restylane.
