Can an old lip piercing displace my lip filler? (Photo)

I had Juvederm 1ML placed in my top and lower lip. I immediately had a lot of swelling and inflammation it has been 2 weeks since my treatment and it seems as though the filler will not settle in the lower part of my right bottom lip and has moved to the other side leaving a visible bump. My practitioner states this may be from the scar tissue from my old lip piercing or the anatomy of my lip??? My bottom lip is slightly uneven and it’s driving me crazy would this be fixable ???
