Yep. I'm much better at pacing then I used to be, but when I get any energy I have a hard time not using it all! Systemic mastocytosis can cause osteoporosis. That's why I'd like to get a scan if this test comes back positive. I see that the drugs used for osteoporosis can cause bone pain, so total conjecture on my part is that NeuroProtek is stabilizing the mast cells in my marrow allowing room for more new bone growth. How's that for a positive spin? I don't know if I'll pursue further tests. I'm not too keen on the idea of stomach, bowel, or, particularly, a bone marrow biopsy (yikes) to prove that it is systemic. Guess I'll cross that bridge when, and if, I come to it.
