Lump under the skin at injection site, not red, not hot — normal?

Warning signs: red streaking from the site, fever, pain getting worse over 48hrs, the lump getting noticeably bigger day over day. Any of those = urgent care.

Oh ok phew. I was googling abscess photos and freaking out.

Sounds like a subcutaneous infiltrate. Not an abscess. Abscesses are red, warm, very painful, and trending worse. Non-red, non-warm lumps after SubQ are usually just undissolved solution or minor tissue reaction. Should resolve in 3-7 days. Rotate sites.

Are you rotating sites? Same-inch-of-belly repeatedly = lumpy belly. Move around. Think of it like a clock face around your navel.

@dr_doubt I've been hitting basically the same spot. My bad.

Also: let the bac water warm up a little before injection, and push slowly. Fast cold injections are lumpier.

Update 4 days: lump is gone. rotating sites now. thanks all.
