Lump on pinky finger

[PinkyBump]

This week I've noticed a lump on my pinky finger. It's not hard and if I pull the skin tight is seems to "disappear" but then pops back up. It looks like the colour of a vein so I was worried about bother a GP incase it's just a normal vein and I've wasted their time but I do get quite bad health anxiety so if anyone has any ideas that would be much appreciated.

Hopeful bump 🥹

Just looks like you've knocked it or it's some loose skin. What in particular are you worried about ?

Does the finger stick out sideways or curl forward? If so, it could be Dupuytren contracture

Definitely not a knock as you can push it down and it doesn't feel bruised. I'm a natural worried about everything I suppose, googling has suggested allsorts including a clot which sounded worrying.

The finger doesn't curl, no.
