The picture isn't ideal, but I suspect this guy has a flexor tenosynovitis. Asking for the cardinal signs kind of gives it away!
Uniform fusiform swelling, holding the finger in slight flexion, intense pain with passive extension of the digit, and pain with percussion along the tendon sheath are the hallmarks of this condition.
