Two days post lumbar puncture. I'm home. I'm fine. Here's the version nobody usually tells you.
Was it comfortable? No. Was it fun? Absolutely not. But I've stubbed my toe harder. Done by someone who knows what they're doing, right needle, right technique, and two days on: not a single headache. Just a bit of an ache in my back, which, frankly, seems reasonable.
The cerebrospinal fluid is now in the lab, being analysed for neurofilament light (NfL), a marker for nerve damage over time. That's what this was all for.
The day after hit harder than the procedure itself. Felt like I'd been kicked in the lower back. Paracetamol, ibuprofen, one quiet day. Two days on, it's almost gone.
Not nothing. But manageable. And knowing that in advance makes a difference.
