4mm Needle Backflow

I find now that I use the 4mm needles for my levemir injections in my legs instead of 6mm I get less lumps and bruises but there is always a bit of insulin left on the skin when I remove the needle. I know this "backflow" is normal but I never saw it when I used the 6mm. I always hold the needle under the skin for at least 10 seconds after injecting so I know I get the full dose but it just seems strange it only happens with the 4mm. Anyone else find this ??

I use 5mm needles and get 'backflow' sometimes and like you always keep the needle in for at least 10seconds and withdraw slowly - so I think it can happen with any sized needle really. But you say this happens every time.........question is, is it impacting your BG levels?

Yes sugars seem fine. No difference to when I used the 6mm or when I don't see any backflow. I guess it's such a minimal amount anyway.

I have been on 4mm for a few years now and do get the occasional backflow. If your BG's are fine then I wouldn't worry it

Yes BGs seem ok. Only see the backflow in the legs. ?? Not sure if that makes a difference. Tougher skin maybe ?
