No stress and no pressure, Wittesea. Just do it when you may have time . No prob. just contributing here, for now... and helping build the list until you may feel up to it.

There are two acronyms that might be familiar to some and just a difference between preferences that some PMs (Pain Management docs) and rheumys (rheumatologists) express.

Here are the abbreviations, which in essence and in effect, mean the same thing:

PSIS
PSIC

PSIS is something I learned from my PM office (and doc); it means: Posterior Superior Iliac Spine.

PSIC equates with or means: Posterior Superior Iliac Crest.

For patients? It seems it all depends on the specialization of the doc which term is the one to apply .
