I have had the same procedure and mine has taken weeks to fill in. I didn't have a blood clot but did have a small hole that from a distance resembled a black head and no amount of makeup could cover it. It is slowly healing. I use aquaphor vs vaseline as recommended by my derm and I like it alot better, less greasy. I had a shave biopsy on my back that left a huge divot and has taken 6 months to finally not be noticeable. I scar really badly and thought it would never go away but it finally has. I'm now facing Moh's for BCC on my nose and I'm dreading it, especially considering how I scar. I'm going to have a plastic surgeon close mine, I guess you could consider seeing a plastics doc if it doesn't eventually heal to your liking. Good luck.
