Symptoms of Avascular Necrosis (AVN):
Many people have no symptoms in the early stages of Avascular Necrosis. As the condition worsens, your affected joint might hurt only when you put weight on it. Eventually, you might feel the pain even when you’re lying down.
-
Pain can be mild or severe and usually develops gradually.
-
As the problem progresses, the symptoms include development of a limp when walking and stiffness in the hip joint.
-
Eventually, the pain will also be present at rest and may even interfere with sleep.
-
Sometimes there is Hip muscle spasm.
-
Pain associated with Avascular Necrosis of the hip might center on the groin, thigh or buttock.
-
Besides the hip, the areas likely to be affected are the shoulder, knee, hand and foot.
-
Some people develop avascular necrosis on both sides (bilaterally) — such as in both hips or in both knees.
