what the hell is this on my finger? callus-like, keeps coming back

i have no idea what could cause this. appeared a year or so ago, doesnt hurt, just feels like a callus. it has grown a little bigger since the start. i used to snip it off with nail clippers (does not hurt, cant rly feel it except at base) but it keeps coming back. i cant get to a dermatologist for a few more months :(
