Hi there, no need to feel dumb at all mentalist, your reaction is completely normal, though it can be alarming for someone new to injecting or someone who hasn't had this experience yet.

I've been injecting meatime (bolus) insulin 3x a day, to cover the carbs I consume, along with injecting a bedtime (basal) insulin for going on 25+ years, in fact, I have an area of discoloration on my tummy right now, where I injected into a vein a week ago. I just stay away from that area until it clears up and try to remember to avoid that area next time.

It happens to us from time to time unfortunately. Our tummies have many veins running through them. Your nurse's recommendation injecting on an angle is a good one, and one I try to remember, sometimes I don't always remember though. Try not to feel like your doing something wrong. Like everything else with our condition, It's all about trial and error.

With regard to the "stinging", I too experience this from time to time. If your using a Flexpen, sometimes it helps some of us to let the pen come to room temp before injecting. I also get "the sting" when using different tummy areas too. Again I try to remember to avoid
that area in the future.

Good luck!

I get bruises from time to time and bleed once in awhile. Last week I hit a vein and injected directly into my blood stream. That dropped my sugar down to 44 in about 20 minutes while eating a sandwich and chips. Just try to be careful.

It happens to me a lot, especially on the right side of my stomach for some reason. The bruising goes away quickly. I have had no adverse reactions however.
