Hi all , before going on a pump I was on Lantus and this happened to me a couple of times and it’s pretty scary. I was 9.8 and injected my 16 units and it bled a lot. Within 15 minutes my sugars were 1.9 , so I was drinking Coke, eating jelly babies and all sorts to try and get it to go up. It took two hours but eventually it did , it was a scary time. I found that I had been injecting after a warm shower and so your veins and capillaries come to the surface more , so I used to avoid them before injecting after that!
