I have lasting lumps along the sides of my top lip after having lip fillers. Is this due to overfilling? Or what else could be the cause? I only had 1.1ml which is standard so I don’t know what has triggered these lumps. I had lip fillers previously and had them all dissolved (5-6ml build up over several years) I had 1.1ml re injected and they dissappeared even though I waited 2 weeks after having them dissolved, then went back for an additional 1.1ml 3 months later and now have lumps, help!
