Sorry to hear you're having issues with your fingers. You mentioned that on two of your fingers it's on the sides of the fingers. The the scaly skin anywhere near your cuticles? The reason I ask is when I developed my first wart on my left thumb I thought it was a callus.
It stayed that way for years and I'd get a manicure and the lady would clip away at it. Well, you know what I've been thru with my fingers. It ended up being a wart there and just spread over the years. Since you said it's hard and feels weird, I don't think it would hurt to make an appointment and make sure that it's just a callus.
Your PCM will be able to tell you if it's a wart or not. If it is a wart they can freeze it right there in the office and hopefully, it will fall off in a few days. Please remember, I have NO IMMUNE SYSTEM that's why my warts ended up the way they did, so don't panic okay.
Let us know if you find out what they are and if they go away on their own, or if you needed the Dr to remove them. Good luck and try not to worry to much about them okay.
