Hip pain in a 19 year old with joint hypermobility?

JHS. Joint hypermobility syndrome (jhs) is an inherited condition of loose ligaments & is better known by doctors outside United States; manifested by ability to oppose thumb to forearm & touch palms to floor with knees locked. Greater joint laxity can be induced by traumatic injury (extreme sports), childbirths, & lifting while turning. See osteopath for therapeutic ideas. Keep muscles well toned.
Needs Seen. Not unusual, but should be examined for potentially serious problems.
Exam needed. Likely causes include capsular strain or labral injury. Snapping psoas syndrome or other tendinitis from the laxity is possible. You need an exam from a hip surgeon to properly evaluate the problem.
