Years ago, when I was in the hospital, I asked a nurse why when she gave the insulin it did not hurt. She said that is because when she gave me the shot, she made sure the eye was facing down. My first reaction was there is no eye in an insulin needle but look at it. Hold the pen so the light reflects off it and rotate it. Soon you will see a very small flash of light, that is the eye. Turn the pen so that this point of the needle is facing down. For some reason when the shot is given when the eye is down the needle slides into the skin easier with no pain. I have been doing this ever since. Ninety-nine times out of 100 it works unless I hit scar tissue.

It is also possible that you are having a reaction to the specific preservative in that brand of insulin

If you try all the above tips and the (problem) remains consistently you could discuss trying a different brand with your doctor

Just about every type of insulin will have 2 or 3 variations from the different producers - exactly the same insulin with just slightly different (add-on's) to make the product proprietary

Insulin is meant to be injected subcutaneously into a layer of fat for slower absorption.

This is common in long-acting insulins like Lantus and Basalgar because they have a high acidity level. Other insulin could sting or burn if you injected into muscle tissue rather than body fat, or if you simply hit a sensitive area or an area used too frequently for injections that need to heal.

Rotate the areas of injection.

Make sure you are injecting into fat.

You can rub an ice cube over the injection area for a while before injection, this sometimes helps.

Good luck.

I try to cool my injection area with ice and then dry it thoroughly. Next I use an alcohol swab to clean it up, make sure it drys. That helps remove the sting. Also I rotate injection site each day. Talk to your dr about the problem. Injections can be a hassle.

It helps to angle your jab at 45 degrees if you are on the slimmer side,90 degrees if a " spare tyre"9
If nothing helps talk to your doc about an injection port rather than inject straight into your skin🐼
