If there is a bluish tint from the injection I would try to have hyaluronidase injected to dissolve it. If there is still a bluish hue after the injections I would try the V-Beam to that area.
I would strongly suggest for you to re-consult a board-certified plastic surgeon. Most likely you would benefit from a trial of hyaluronidase followed by a trial of injected steroids if the hyaluronidase does not achieve the desired result.
All the best!

If placed too high in the skin, filler can last for years because the body's enzymes don't have access to break it down. If the bluish tint is caused by filler, a trial of hyaluronidase is the best solution. If the lumps go away, then you confirm that the lumps were residual filler. As long as your next injector takes care to inject product in the correct plane, it should not happen again.
Although it is unlikely that there still is filler in your lips, it sounds like there might be. I would give hyaluronidase a try. If this doesn't work, the vbeam might be helpful for improving the color.
