Just another update: Yesterday marked 7 weeks since my left BHR, and it's unfortunately not keeping pace with the right side. I still have pretty good groin pain on the left side, much more difficult with adduction. I'm still limping, straight leg lifts are painful and difficult, sleeping with a pillow between my legs, difficulty balancing on just left leg, having to sit and struggle a bit to put on pants, shorts, etc. At this point the first time around, I was doing great, and only a few days away from my recently repaired hip taking a primary role as the other hip got resurfaced. My right hip did fantastic at carrying the load when my left went out of commission. My left is nowhere near ready to do the same if my right were about to go down.
Last week also saw an unexpected return to medical care, as Tuesday evening my left hip began stiffening up, with pain also in my lower back and abdomen on the left side. Eventually the pain got to the point that I nearly passed out, and I though perhaps I'd dislocated it or somehow otherwise really screwed it up, so my wife took me to the ER. Morphine eased the pain to manageable and a CT scan revealed a hematoma of the iliopsoas and accumulation of fluid in my abdomen ("bunch of blood" per the ER doc). We went back to see my surgeon the next day and he said it was possible that this was "old" blood that had been sitting in the muscle since surgery, blocked by a clot that had just decided to liquefy, releasing it, but either way the best approach was a simple wait and see. The abdominal pain stayed pretty intense for a couple of days but has since abated and is now quite minor, but the groin pain remains unchanged. Based on what reading I've done, it sounds like trouble with the iliopsoas post resurfacing is fairly common, and my hope is that it is simply a healing process from surgical trauma rather than something more persistent such as a socket not countersunk into the bone, resulting in abrasion of the muscle. I always expected that one of the hips would heal more easily and quickly than the other, and this certainly seems to be the case.
