Should I go to the doctor?

Over the past three weeks, these red bumps have been forming on the joints of my hands. They’re not filled with liquid like a blister, they’re kind of firm, which is why I thought they were calluses from notetaking at college, but they’re forming on places that aren’t consistent with holding a pen. They’re pretty painful, but it comes in waves, and it’s becoming difficult to bend my thumbs at the first joint. Are they just weird calluses or should I go in?

(sorry was on call when I took these lol)
