A felon is characterized by a fingertip pad that is erythematous, tensely swollen, and very tender to palpation. There may be an associated puncture wound or paronychia.

Usually, due to the septae, the infection is usually contained to the pulp of the fingertip. If the infection has spread to the flexor tendon sheath, bone or joint, spreading of the infection may be visible. [4]  The point of maximal fluctuance may be on the volar aspect, raadial or ulnar surfaces.
