I had a lower body lift almost 9 month ago and started experiencing a pain on the back scar. An area in the back of my scar started to become like a blister and then opened up. I did experiance this at the begining of my PO in another area but is it normal for it to happen at this time? I am apply suldadiazine cream and taking antibiotics to avoid infections. Fluid was coming out when the blister first poped.
