Osteomyelitis involving the diaphysis of distal phalanx is a common complication.

The most serious complication of felon is acute tenosynovitis, which may result from contiguous spread of infection. This can be iatrogenic from inadvertent nicking of the flexor tendon sheath during drainage.

Other complications include skin necrosis, deformity of the fingertip, septic arthritis, and instability of the finger pad.
