Sore thumbs that peal dry callus and start over

Hi I'm a 24 year old lady and my finger tips keep pealing and then dry and get hard. It started a year ago on my two pointer fingers only. I blamed it on the chemicals and all the hand washing. I would put lots of lotion or teatree oil on it but it only soothed the burn. When I quit the Job it went away a month later. Six months after that I broke my thumb nails really short and it started on them. First pealing then the Harding almost like a callus. My nails grew back and I use lotion and oils iv even filled it down and put cuticle oil on it several times a day. It won't go away and hurts. It's weird how it started on my pointer fingers went away and six months later is on the tips of bolth my thumbs. Nothing works please help or let me know what it could be. No one I know has ever had it so I went online
