My orthopedic surgeon, my neurologist and my physical therapist have all been caring, supportive, and have offered as many potential solutions as they could. The pain management specialist was a Useless Wanker, but you already knew that. The steroids helped for a blissful few weeks, but the pain is creeping back.
We are all pretty much at the end of our ropes with frustration (except for the Useless Wanker, who didn't give a rat's ass). But now there is no consensus on what is causing the pain, which should have been relieved by the replacement.
The orthopedist says it is neurological. Go to the pain management specialist.
The pain management specialist (Useless Wanker!) says it is neurological. Go to the neurologist.
The neurologist says it is orthopedic. Go to the orthopedist.
I am going in circles.

HELLLLLPPPPP!!!!!!
(And mind that you don't cross me or you'll end up in my blog as a Useless Wanker. lol)
