so me and my bf were sanding a skateboard bc we’re painting it and stupid me didnt have gloves on at first so i sanded my fingers. and most them healed fine but my ring and middle fingers have these weird blisters on them and they were almost gone like there was literally only 2 left on my ring finger. then i got stressed out and started crying and theyre back. im so confused. they arent itchy or painful and you cant pop them theyre hard. ive been looking online to see what it is and nothing looks like it so someone please help im going crazy :/
