Six years ago, the only FDA approved products in the US were collagen based. These products were Zyderm, Zyplast, Cosmoderm, Cosmoplast and a now discontinued product called Dermalogen. While these could have caused lumps, it is extremely unlikely that they would cause such lumps like you are describing.
Sadly, you were probably injected with Silicone, which is NOT approved and has never been approved for facial injections. This is the reason to only have FDA-approved material injected into your face and, furthermore, to avoid anything that promotes itself as permanent or semi-permanent.
Ones to avoid now that are, indeed, FDA approved are Artefill and Sculptra. These can cause some very concerning problems. Others that are undecided/jury out are Radiesse and Evolence. While you can certainly have them done, they don't have the track record yet of Restylane, Perlane and Juvederm.
You need to get a second opinion from a dermatologist in your area with a good reputation.
