Hello there. No, I have no clue to what it is you describe. What interested me is that with all the time I have spent trying to learn medical terminology and definitions, you posted some things I knew nothing of, until I looked it up.

The level of informed commentary I happen to find herein has impressed me. So.... Could I help?

One thing I do know (who knows, maybe it could help) is that GCS-F (generic Filgrastim, brand name Nupogen) injection, which is used to boost neutrophil production, often causes "bone pain", which is said to be due to marrow volume expansion and/or contraction. The pain seems to pulse with heart beats. So, maybe your pain indicates marrow volume change? Therein may be a clue.
