I'd like to see a research study on scar tissue caused by injections. Do you get more or less scar tissue pumping? Does blood sugar control affect the rate at which your body scars? To what extent does scarring accompany absorption problems? What percent of diabetics have absorption problems after 15 years of insulin? To what extent does scarring affect A1c? To what extent does rotation minimize scarring?
In the last 24 hours, I injected myself 11 times. Yump, eleven times. Granted, that's about double my mean, and about treble my median, but days like this are still not that rare. Sometimes I wonder, when I do a shot before and after meals (which is what I do with most large meals), is the potential scar tissue worth the control?
I don't have any diabetic scars. I have been injecting insulin for just under eighteen months. 18 months x 30 days per month x 5 shots per day = 2700 shots. I think that that's probably a slight overestimate of the number of insulin shots I've had. I think about the fact that diabetics at one point tended to take only two shots per day or so, and still got scar tissue within ten to fifteen years. If we figure 2 shots per day for ten years, that was only 7300 shots to get to scarring. I'll be at 7300 shots in another three years.
Some days I find myself pretty desperate for a site that doesn't already hurt. What will it be like when instead of bruises I have scars?
