I have the same problem with the fatty sacks on my stomach from my previous ignorance about rotating my sites, they won't go away as much as I would like even though I have stopped using my stomach as a site all together for a while now. Any advice to help it go away?
I think you are talking about fatty deposits that can occur when injecting insulin, particularly if the person always uses the same locations for injecting insulin.
It is important, when injecting insulin to rotate the injection sites so that insulin is never injected too frequently into a single location.
