I see my physiatrist on Wednesday to review my withdrawal, and the discussion will come to "OK, what do we do if pain spike?" This is what we referred to as breakthrough med in his lexicon. Then, it was Decadron. The old B.M. for when I was pre-surgical. If it happened, the 9 or 10 out of "I wanna die" pain, then I was to take the Decadron. It is a powerful steroid supposed to be analogous to a powerful injection. Can only be used sparingly. I still have my supply. Will ask then report.
Time will tell,
