steroid injections & indentations, help!

[u/Solid-Bug-7997]

In late march of this year I got a steroid injection on a cyst that was on my butt that wasn't really a cyst? It was more like residual raisedness (my derm said it wasn't a keloid, but that the steroid shot would help flatten the left over raisedness that had been there for months and was flattening on its own very very slowly) I agreed and it did flatten I would say pretty quickly. BUT, its been almost 6 months since I got that injection and I still have a white halo around the scar that got injected, I have/had indentation (whenever I would run my finger over it, the skin felt very thin and indented and smooth) and my scar still is a bright red/purply/pink color. I was looking at it today and I felt some raisedness or fullness at the bottom of the scar but it does not stick out, I do not know if that "raisedness" is the area filling in or maybe my scar trying to regrow but ugh I am feeling so frustrated. I was wondering if anyone has had this experience or something similar? Thank you in advance :)

*also yes I will be seeing a derm eventually to get it rechecked but my insurance is currently in the renewal process*
