What could cause my lateral hip to hurt after sitting for awhile? when i sit straight up, not reclined, my hip hurts. other movements also cause pain.

Hip pain: The 2 commonest causes of these symptoms are bursitis or osteoarthritis. A week of anti-inflammatory medication like ibuprofen or Aleve may eradicate bursitis but pain of osteoarthritis would recur after discontinuing the medication. An orthopedic specialist can evaluate and treat you. An xray of the hip would show any osteoarthritis but is often negative with bursitis.
