@ottadv Hello - you story could be mine before hip replacement.
Hip, back and even knee pain - was treated for bursitis of the hip and back pain - shots, PT, stretching, rest, ice, exercise...for 5 years. Each of these was a "bandaid" - worked for while, then less and less, finally not at all. I was only in my early 50's, slender and active - nobody thought of the joint, until I could no longer walk up stairs normally and x-rays of my back revealed significant damage both hip joints. Both hips were replaced (6 weeks apart - I recommend a longer wait) and I had total relief, including the lower back and knees. Turns out limping and compensating stresses the entire lower body.
So, when the time comes that the shots don't provide comfort, go for it.
