How long have you been on insulin?
I started off about three months ago and would often get yellow bruises on my stomach. I don't get it as much now so am guessing that my stomach is getting used to it. Like you occasionally I also get small hard lumps about the size of a pea sometimes. I also find that they itch and take a long while to dissapear. To start with, I didn't feel any stinging when injecting, but now I have to try 3 or 4 places before I can find one that doesn't sting. I assume that I am running out of places that haven't already been stabbed.
Can't offer any advice but like you I would be very interested to see what others come up with.
On the plus side I have been told that they will be starting to phase tablets in and insulin out within the next 3-4 weeks so hoping that you will be the same. That day can't come fast enough.
Lets see what others come up with.
