Is induration or hardened lumps common after Cellfina?

I have hardened lumps which are pretty painful on my left thigh, which is the area that the P.A. did. I'm 10 days post-op, so is the pain like this normal? The right leg looks and feels great, done by MD. It barely has any bruising. I called Mertz who owns cellfina... apparently it legal is in my state for a PA to use cellfina under supervision. I'm just hoping that my leg isn't permanently damaged .
