Early osteonecrosis symptoms are similar to those associated with arthritis. Osteonecrosis sufferers may experience pain and aching of the joints when performing normal activities. The discomfort is oftentimes sporadic and short-lived, preventing many osteonecrosis sufferers from consulting with a doctor in regards to the issue. As such, osteonecrosis often goes undiagnosed for a lengthy period of time until the occurrence of increasingly painful symptoms eventually elicits a sufferer's response. Symptoms and signs of osteonecrosis include.

1. Pains: Intermittent or persistence pains, pains are getting worse after walking or activities.
