Hi Again,
Yes, I hope that you can have the problem remedied without surgery, however your symptoms are very similar to a relative of mine that eventually had a labral tear repaired, solving the problem.
Symptoms that change position can be due to the owner (you) changing body posture subconsciously to give the damaged area some recovery time. Such postural change is not as efficient biomechanically
and alters symptom positioning. There may be a nerve entrapment, however this should not give you a click or stuck feel. If you know someone with a Sacro-iliac joint belt, give that a try, making sure you put the belt
in the correct position and do it up when laying down.
Good luck.
