Sorry to hear of your pain...
An x-ray is to look at the bones primarily..So it's good news that you don't have any hip fractures or something like that!
Yes, an MRI would be the next step to see if there is any tendon/ligament/muscle issues....
It could easily be bursitis...Did the Dr. mention that at all? Does he have you on any anti-inflammatory medication or tell you to ice the area or offer Physical Therapy?
Do you do any daily exercise with walking or light weights? Or are you mostly inactive?
Does it hurt most through the night and first thing in the morning? Or more after walking?
Not that I, or anyone on here is a Dr. of course....Just asking a few questions to better understand when this started...
The main thing is ruling out anything emergent...but you don't say that you had any type of fall or accident....so it's more likely it's something muscular with inflammation as this is very common...
