After delving a little more deeply into the "other side" of PHC conflict, I have decided that the whole mess is, indeed, misunderstanding. Unfortunately, it is a strongly rooted misunderstanding, so it is harder to resolve.
Meanwhile, good news for me! My knee is not in serious trouble. It will need no operations, no cuttings and slicings! It just has a tight ITB, which is a band on the outside of the leg that goes from hip to knee and connects to muscles. When you stand up with this band tight, it rubs over the outside of the leg bones with a *snap* feel. It also pulls the patella in the front out of alignment, etc. No doubt it is because my quads are weak. But whatever! I am so happy to know this! All will be well! Hooray & yahoo!
