A. Proximal inter-tarsal joint swelling of big toe is related to a different condition, such as gout or hallux valgus. B. Non-painful enlarged interphalangeal joints are not typical of Heberden's nodes, which can be painful and associated with osteoarthritis. C. Heberden's nodes are characteristic of osteoarthritis and occur at the distal interphalangeal (DIP) joints. They are often seen as bony lumps and can cause deviation in the joints. D.
