Sculptra Nodules/Bumps

Dear Dr. Liu Ta-Ju, I had a Sculptra treatment last year in September. In October I developed two bumps/nodules on the temple and cheekbone. The one on the temple is way more visible in daily situations. I already tried one saline injection in October and a subcision treatment in November for this. It didn’t help at all. If anything happened, it dispersed the lump a bit. Since then I hadn’t done anything else no more. The nodules are not inflamed and they are not painful. I urgently want to avoid steroid injections because I am clearly afraid of atrophy. I want to avoid this at all costs. Also I got the feeling that the subcision led to a slight volume loss on the forehead. I am really devastated and hope so much that you can maybe help me. I just want my old face back.
