If your injections were recent (within the last couple of weeks), these are normal and may be improved with some massage. If not recent then schedule an appointment with your injector to discuss having the filler dissolved. However, keep in mind that it can take as much if not more skill to dissolve filler than to place it. Best of luck.
most doctors use different technique in injection fillers. It is possible that your doctor used bolus injections with the filler and you may possibly feel the lumps Under the Skin. As long as the lumps are not visible, you have no discomfort and your result is pleasing, you should leave it alone. If on the other hand you see and feel the lumps under the skin or there is discomfort, you should definitely return to the treating physician and let him or her resolve this issue.
