Do you get buzz sensations in your fingertips?

Addiction or relief? Anyone else get a minor sensation in their fingertips that make you have to press on them to relieve it?

I’m finally trying to work out what this is!! For decades I’ve presumed it’s a habitual thing, similar to biting nails or cracking joints but now thinking it could be PSA related. I can’t work out of the sensation makes me want to press on finger tips to relieve or if the sensation comes from me doing it ?? Like nail biting, I usually only realise I’m doing it halfway through. The sensation feels like a ‘buzz’, like when your feet are tired. It’s not a pain but if I try not to to the pressing then it’s really annoying and gets worse. To relieve it I press down on the finger tip, use a file or object to ‘clean’ the cuticles, use my teeth to press down.... very strange behaviour indeed! So if I get a reply saying “I know what you mean” I will feel better in knowing it might be a PsA thing. If not? Then I suppose I have to put it down to a psychological thing....
