Not for me, and practicing atleast that much too. My callus mostly just builds up and I have to cut them off. I do have a ton of hang nails and if I start pulling or biting them off instead of clipping I'll get a sore that will make the top layer of my callus peel. Sometimes the callus get so thick that my ring finger nail gets long and my bends with that finger start being crappy. Ill get bummed about my playing sounds like crap and I will realize eventually I just gotta trim my nail back. Sometimes I shave it off just to make my fingers sore again to help me practice a lighter freting technique.
