Avascular Necrosis Symptoms
Aseptic necrosis begins as a painless bone abnormality. It can remain painless. The involved bone often later develops pain, especially with use. Pain in the affected joint is usually the first symptom of avascular necrosis. When the lower extremity is affected, this can lead to a limp during walking. If the hip is affected, groin pain is common, especially when walking. As the ball of the hip collapses with progression of avascular necrosis of the hip, pain can persist in the hip after rotation or weight-bearing with walking.
