Lumps developed on my cheeks 4-5 weeks after Bellafill injection. Will they be permanent or temporary?

54 yr old male sunken cheeks got Bellafill: 3 vials injected 2 months ago, higher up on cheeks, then a month later 2 more vials lower on the cheeks. Recently noticed swelling/lumps on the lower cheeks, on right & left sides of lips. Are they granulomas? Nodules? Might they reduce or go away? If they are going to be permanent, what caused it? A reaction? Or injection error? And then the question is, what can be done? (If skin in photos looks strange, I just had a chemical peel a day ago).
