just the sustained runin bothers me.
any idea what it really is and is there a way to get byond it or is this just a permanent limitation of our hips?
I've sure you have read through some of the previous posts. There has been discussion on this. I had posted previously on this topic an article about a study that claimed that cobalt levels in marathon runners with resurfacing did not change with activity. That article no longer exists on that site so I'm doubting its veracity.
The leading theory in my opinion comes from Baby Barista who quoted his surgeon, Dr. Pritchett. He said that the pain is due to increased cobalt levels that spike right in the fluid around the hip during activity. This can cause a local tissue reaction in some people. The body works to excrete the high levels of cobalt and the pain subsides as the levels drop.
I have the same issue with pain as well - but only sometimes. In 2013 I ran in a 5K pain free at 11 months post op. A year later in 2014 I ran in the same 5K coming into the race more fit. But the pain began at about the one mile mark and I had to walk several times just to finish the event. My time was much worse than the previous year. That defied explanation.
Cory Foulk, a well known Iron Man competitor explains he had problems with pain during running due to ions shedding (increased cobalt levels). He says he found a way to fix the problem in that a proper warm-up is the key to running pain free. See earlier post for a link to that. I tried many different variations of warm ups as he describes. Warming up had no effect for me on my pain during running.
Aside from my one 5K-a-year endeavor, my activities include competitive soccer which I returned to six months after my resurfacing. Invariably if I were in a match more than 60 minutes, I would start to get that deep ache and I was in pain for up to a couple of hours after. But this year I started watching my hydration in the days before a match. The more consistent I stayed properly hydrated, the better my hip remained pain free during soccer (regardless of whether I used the Cory Foulk warm-up or not).
Just recently, playing pickup indoor soccer, the pain started creeping in at about the one hour mark. I immediately left the pitch and grabbed some water - a lot of water. I quickly drank at least a 16 oz bottle and then a little more from a second bottle. I waited a few minutes, stretched a bit and then returned to the pitch. The pain was gone and did not return.
So maybe there is a correlation between fitness, proper hydration, and personal tolerances to spikes in the cobalt levels that play a role in pain during running. If you have no idea what your hydration has been the days before you try and run you could find yourself in pain.
