I had a hard lump after BBL and received around 12 Kenalog injections. Did this cause my gluteal muscle to die?

I had a BBL, immediately after I had severe pain, I went back to my surgeon who gave me an injection. This helped for I while. I went back because the pain was worsening again instructed to get Kenalog injections every month which did not really help. I eventually went to Kaiser got an MRI, the Dr. found a lipoma 6X3cm and decided to biopsy. After surgery, he said the lipoma was very deep and that I had huge chunks of dead gluteal muscle which had to be removed.
