Since you would be injecting only into the skin (that is how insulin is done)... I am concerned that the pink is still there.
Is it hot to the touch? With synthetic insulins, it is possible to have an allergic reaction=pink.
Also to have an cellulitis which may be pink. There are just not alot of large blood vessels in the skin where you inject. Do you pull back before releasing the insulin? One is supposed to do that.
Some people develop a deterioration of the fat layer, with repeated injections.
I'd have a doctor look at it. Maybe you could get off the injections now? Also consider the Glumetza...metformin without the horrible GI diarrhea.
