Your discussion of systemic inflammation affecting metabolism, blood sugar levels and normal insulin resistance applies also to injected insulin resistance as well, IMO. My BS levels have been higher in the last 2 weeks. Here is why.
Some readers will recall my brief mention of the inflammation in me resulting from missing a single shallow step on exiting our elevated table at the magic show of David Copperfield at MGM Grand ~ 2 weeks ago. A rather hard, and painful, fall on my rear was the result. Mobility is OK, nothing appears broken, but Vascepa and twice daily Alleve did little to relieve pain. Heating pad to increase blood flow to lower back for 1/2 hour helped, but no total, consistent relief from pain. I increased amounts of injected insulin to control BS levels with mixed results. Had a 2nd hour treatment by local specialists this morning. Muscle stretching and manipulation, and initial electrical pulse stimulation. Some nice exercises to stretch the inflamed muscles w/o evoking pain are now in my daily regimen. Climbing flights of stairs in our condo is not painful, and helps with BS control as well, per usual regimen I used with colder weather in D.C. We are getting back to normal.
