Hard Bumps After Sculptra on Forehead

I had sculptra injected into my temples, three years ago, and all I was left with were four unslightly bumps. It did nothing to plump the area. After three years, three, of the bumps, have finally diminished in size, and are not that noticeable. They sometimes still resurface and I have to squeeze the fluid out of them. One is still always present. Two steroid injections have still not gotten rid of it. I massaged five times a day, or five minutes, for one week, immediately after injections as directed. So, I disagree that sculptra in this area cannot cause long lasting, unsightly, bumps that are very hard to get rid of. The area is so tight to the bone that it seems like bumps will show more in that area if they develop after sculptra. I hear that Radiesse in that area is less likely to cause bumps.
