Hello. Wednesday my son had pain in his ankles and had difficulty walking. We thought is was growing pains. The next day he had severe pain in his hip. Took him in and he was admitted him for rule out hip infection. They aspirated fluid from his hip joint. Very little was aspirated from his hip and cultured which grew nothing. Initially his his wbc was 12.9, crp was 4.1 and esr was 18. The day after fluid was aspirated he was able to walk without any pain. He was discharged home. Later that night he developed pain in his opposite hip. Gave him Motrin comforted throughout the night. In the morning, pain had decreased and he was able to walk. Later that evening he developed pain in hi shoulders and hand. Again, gave Motrin and tlc through the night. Have labs drawn on yesterday and he has a increase in his esr to 29 and crp to 4.9. Any thoughts?
