A 35-year-old woman who has been in recovery from alcoholism for 2 years presents with chronic hip pain. She reports that as part of her commitment to her recovery, she began exercising regularly about a year earlier. After a month or two, her hip began to hurt when she ran on the treadmill. She stretches, has had a physical trainer check her form to ensure that it is correct, and rests adequately between each workout. Six months ago the pain began waking her at night, and now it is constant. She is not aware of any injury to her hip and has no other outward symptoms. Which of the following is most likely to be the cause of her pain?

Osteonecrosis

Explanation:

Osteonecrosis: The term "osteonecrosis" is defined as a disease that is caused by the reduced or decreased blood flow to the bones in the joints of an individual. It often leads the bones to break faster due to the lack of blood before the body could make enough new bones. In osteonecrosis, the bones of an individual start to die as a result of a lack of blood and results in bone break down.

In 80% of people, osteonecrosis generally heals without treatment if it gets diagnosed at the initial stage and has the least affected parts.

In the question above, the statement signifies "Osteonecrosis" as the cause of the woman's pain.
