Help - unresolved swelling at injection site (hyaluronidase)

I had filler to the tear trough a 6 wks ago (revanesse ultra). This blocked my lymphatics on the right side, causing extreme swelling. As a result, I have done two dissolver sessions with hyaluronidase - with some improvement. However, I now have 4 swollen lumps at each of the injection sites where the dissolver was injected. I am told that it's just my body's reaction to a needle (inflammation), but the marks remain after 3 weeks, unchanged. Please tell me what they are and how to treat!
