Someone I work with (female, 25 years old) had inflammation on her knuckles that is similar to what you describe. This was after her second shot - not sure if it was Moderna or Pfizer, but it was MRNA. She's fine and it eventually went away, but it's certainly interesting. She doesn't have any autoimmune disorders that she knows of.
