Late to the party, here, my friend, but my symptoms were virtually identical, causing me to chase every non-surgical treatment I could identify. I finally gave up the ghost and had an MRI, and that doctor looked at me with amazement and said “I don’t know how you are walking without screaming, as your hip is bone-on-bone.” Upshot is that you don’t know for sure what’s going on without the MRI.
For me, I had the option of a conventional hip replacement or a “resurfacing” where they just resurface the socket and the ball with cobalt and chromium, respectively. Resurfacing is a tougher procedure, requires a real expert for it to be right, and typically requires a longer and more painful recovery. Moreover, it’s not permanent.
You likely will have to have a complete replacement in another 10-20 years. The upside is that if it works exactly as it should, you can return to all of your former activities without restriction in 3-4 months. I was a runner, and I wanted to keep running. My resurfacing didn’t achieve that for me entirely. I make it a mile and it starts to hurt again, every step. That said, everything else goes as it did previously, and in fact, my squat actually improved quite a bit after the resurfacing.
A complete replacement–where they chop off the head and replace it with a new metal piece and are much more invasive with the socket replacement as well–historically was not as successful in allowing one to return to full use of the hip after the surgery. However, in the past few years, complete replacements have improved dramatically, such that many surgeons now advocate them over resurfacing not only because they are permanent, but also because they come close to equaling the functionality of a resurfacing. And the recovery typically is faster as well. I think if I had to do a hip today, I probably would opt for the complete replacement.
Hopefully, you are not facing hip surgery because however you chalk it up, it sucks. But you won’t know one way or the other without the MRI.
