The good news is that these issues can be remedied. I agree with the advice to give this another few days to a week. However, if you have not yet seen your injector since your treatment, I'd recommend following up with them now. They can evaluate your lips and advise you on whether this is normal for the type of injections that they do. If they feel that there truly are lumps of filler and not just swelling they likely will offer hyaluronidase treatment to remove some of the filler causing the lumps. I hope this information is helpful.
