Still click at almost 3 years post op. No pain w/ mine ... just the click, pop or what ever you call it. I get a chuckle out of it when it happens at work. The guys around me starting freaking out. "You okay!?" Can just about do it every time I have a big yawn and stretch.
Me being the sick little fella I am, I'll ham it up with a few of them and tell them I think I just broke it in half. They tell me it's like when you hear the story about a guy falling off the bicycle seat and hitting that bar that runs from front to back in they're happy place. (ouch ... just squeezed my legs together!)
Being serious, if you have pain with your pop, I'd probably call the doc and run it past them.
