Injecting myself - how to get the hang of it

[Daisy2990]

I'm on blood thinning injections. I did my first one today on a shallow angle like the midwife showed me. I ended up with a lump under the skin which stung for quite a while afterwards. Not mega painful but still quite sore. Does anyone have any tips on how to avoid the lump/ pain?

Also, I need to change the time of the injection - first one was at 3pm which is no good due to the school run. I'm thinking about just doing it slightly earlier each day to work it back to a more convenient time. Is this the right way to do it or should I just skip half a day and then start again at the time I want them?

Also if you face the beval side of the needle upwards it hurts less.

Thanks @wiggler1

I have a high BMI so that definitely isn't the reason I was told to do it at 45. Anyway, I injected at 90 degrees yesterday and it was psychologically easier for me to do, and less painful afterwards. My midwife hasn't got back to me about it, so I'll stick with that for now.
Sharps bin is sorted via my GP surgery, although TBH I'm not sure why they are allowed to give out injections without sharps bins at all.
