@Dan1987 Is it the injection that is hurting? You say it just hurts sometimes in your stomach - are you rotating sites? Sometimes we can just be unlucky & hit a spot that hurts. If you stomach is uncomfortable, maybe give it a rest and try your upper outer thighs, yout upper arm, love handles. See if you can find somewhere a bit more comfortable, or at least, less uncomfortable.
Make sure you are using the smallest needle possible for you (4mm is the smallest) and a fresh needle every time. Make sure you are rotating your sites and injecting in somewhere ideally with a good bit of padding.
@Tulip01 Lantus we inject is acidic, so unfortunately it just does sometime sting.
How much are you injecting? If it's a large dose (over 20) and the lantus is stinging, it might help to split it up into 2 separate injections - so (if you are doing for example 20 u) instead of sticking all 20 in one place, do 10 in one leg and 10 in the other.
Injecting somewhere with a good bit of padding might also help with the sting - I would inject my lantus into my thighs or my bum cheek (cos I've got plenty of padding there) and I found that the sting bothered me less there than in my stomach.
I also found that it helped to not move too much after taking my lantus so do it in bed and then stay in bed and fall asleep - I'm pretty sure that's just because I'm a drama queen, but getting up and walking round on the leg where I injected seemed to make me more aware of the sting. You could try numbing the area with ice - it would give you a different kind of sensation to focus on instead of the sting. Someone else has mentioned scratching at the same time as injecting for the same reason - you focus on the scratch over there on your knee so you don't notice the lantus going into your thigh.
Sorry, it kind of amounts to just put up with it (which isn't awfully helpful) but maybe if you experiment with different places you will find somewhere where it isn't so uncomfortable to inject. Or if you think it's the acidic lantus which is causing actual pain, rather than just discomfort, you could ask about a different basal (levemir) - I'm not sure it's good enough to be told "a bit of pain is normal" youre doing it everyday forever, you shouldn't be putting up with actual pain if there is an alternative.
