Second Time Did Mesolipo

First of all, I apologize for my bad english as its not my intermediate language. Today I did my second treatment of mesotheraphy, i did the first treatment a 1 1/2 months ago on my cheek, I'm happy with it, but not really happy when my cheek gained fat back, I'm a petite girl but my face is round shape and I have a massive double chin, So I found this one beautician that offer me lower cost for mesolipo treatment for my double chin, And i did it today, What I really concerned is about this swelling, I'm getting married this saturday, and my neck did swelled right after the treatment which I am that easy to swell. On my first treatment, its not that bad, my cheek did swollen but only for two days, but for this second treatment I did it with quite alot of volume. Its freaking me out now, I'm really scared if the swelling would not reduce. Anyone help me! should I buy the swollen medicine from the pharmacy???
