Hi there!
Well, without a clinical evaluation it would be difficult to determine the cause of your symptoms. Likely possibilities that may need to be considered are dislocations/ subluxations, injuries tears to the labrum/ ligaments/ tendons, fractures, growths/ masses etc aside the inflammation. I would suggest getting this evaluated by an orthopedician for an accurate diagnosis and appropriate management.
Hope this is helpful.
Take care!
When you see the doctor be sure to ask for a MRI of your back this sounds like sciatica and you could have a pinched nerve or disc issues.
