Could it be related to sympathetic nervous system?

Edit: the wrinkles from sympathetic activation :

"Pruney fingers grip better

Theory suggests wrinkling of wet digits evolved for a reason.

Like tread on a tyre, wrinkles on wet fingers channel water away from the fingertip.C. Weekley/Getty
The wrinkles that develop on wet fingers could be an adaptation to give us better grip in slippery conditions, the latest theory suggests.

The hypothesis, from Mark Changizi, an evolutionary neurobiologist at 2AI Labs in Boise, Idaho, and his colleagues goes against the common belief that fingers turn prune-like simply because they absorb water.

Changizi thinks that the wrinkles act like rain treads on tyres. They create channels that allow water to drain away as we press our fingertips on to wet surfaces. This allows the fingers to make greater contact with a wet surface, giving them a better grip.

Scientists have known since the mid-1930s that water wrinkles do not form if the nerves in a finger are severed, implying that they are controlled by the nervous system."

Yes I’ve had this on and off for a while. I’d heard mild dehydration causes pruney fingers too which would make sense with a lot of us having issues in that area.

For all of those who have these vertical wrinkles on the finger pulp, we should try the skin wrinkle test to see how we react.
We must put the fingers 5 minutes in water and fingers should look like:

I have this very slightly on right middle finger and right little finger. But a little while ago I noticed them on most fingers. So some have gone away over the last two, three weeks. I had carpal tunnel very badly with a semi paralysed right hand (thumb and index finger paralysed) in 2012, but it's better now, though index finger still a bit numb.

I also had Beau's lines quite deeply on left thumbnail only when my illness began and for 15 months. For 8 weeks now they are fading out which I take as a good sign.
No EDS.

My mother had severe rheumatoid arthritis, and her fingerprints just disappeared. She used to laugh about it and say she'd make the perfect criminal, if she could only walk.
We used to joke here about financing our medical treatments through crime as we didn’t have fingerprints! Anyone but me have trouble using their phone’s fingerprint recognition to sign in?

From Dr Paul Cheney

Very unusual is the loss of fingerprints on many of the fingers; police departments report it's very rare for fingerprints to be obliterated, yet nearly 40% of CFS patients have some fingerprint obliteration, and 10% cannot be fingerprinted whatsoever. This appears to be related to a periarteritis secondary to fibroblasts congregating in the distal circulation. Cheney suspects that CFS patients, mimicking in many ways a scurvy process, might have scurvy contributing to fingerprint obliteration.

Also there is a page on MEpedia about finger print changes https://me-pedia.org/wiki/Fingerprint_change

i think you are right, because my vertical wrinkles disappear after a bath, and disappear after the night. It only comes back after I am awake for hours...

I noticed something else that might be wrong with me: I put my fingers 10 minutes in water this morning (not cold nor hot), and...Nothing happened...so my skin wrinkle test may be negative...

OK, weird, now it's not just my fingerprints disappearing, but my posts about my disappearing fingerprints... I know I replied to this thread. I think I was the first to reply to it. And, @pattismith responded to my reply by asking how I knew I was "unfingerprintable". To which I replied with a story about trying and failing to get fingerprinted for a license application. Where did my posts go? :wide-eyed: And where did @pattismith's reply go?
